How to install, update and remove Chromium, on Windows?
About updates: your settings, bookmarks, extensions, history, passwords, cookies... will be saved. Do not worry!
For automated updates, choose one of the Chromium #updaters

Installer
  1. Download the EXE executable file (This is a 7-zip self-extracting archive. So you can unzip it to see its content)
  2. Close Chromium browser if opened
  3. Execute this EXE file
  4. Wait for 2 or 3 seconds (Installation is silent)
  5. Open Chromium browser. It is updated!
  6. To remove it definitively: use the standard way (or a software like Bulk Crap Uninstaller, Geek Uninstaller, Revo Uninstaller, Ccleaner...)

Archive
  1. Download the ZIP archive file
  2. Close Chromium browser if opened
  3. Unzip this ZIP file
  4. Delete all the files from your installation directory
  5. Move the files from the unzipped directory to your installation directory
  6. Open Chromium browser. It is updated!
  7. To remove it definitively: delete your installation directory

Portable
Note: Chromium has #secure-preferences feature based on the machine SID. So extensions, certificates and passwords are not portable. The best way to migrate your data is to synchronize them.
  1. Download and unzip "chrlauncher-xxxxxxx.zip"
  2. Execute chrlauncher.exe (chrlauncher is a free and open-source Chromium launcher/updater)
  3. Close Chromium browser if a notification displays a new version
  4. Click on the "Download" button
  5. Wait for download and automatic installation
  6. Open Chromium browser. It is updated!
  7. To remove it definitively: delete the chrlauncher folder

Package
  1. Install Chocolatey (A free and open-source package manager) in command-line
  2. Chromium will be automatically updated via Chocolatey (using our API)
  3. To remove it definitively: use the "uninstall" command-line via Chocolatey
Windows XP, Vista
Since version 50, Chromium is not available on XP and Vista. For help, version 49 works fine.
In addition, if you have an old CPU without SSE2 support, version 34 is the last one (portable, builds before 253860).

How to install, update and remove Chromium, on Linux distributions?
In most cases, Chromium is directly available in the official repository of each Linux distribution. So it is easy to install, update and remove it via the integrated software/package manager or in command-lines.

There are other ways like:

Notes

Obviously, you know this site is not the Chromium official website. As a regular user (not an expert), I created it in 2013 because there was no easy way to download good and stable releases of Chromium, on Windows. I try to keep it as safe and fast as possible! ;) This is absolutely a non-profit site. Please, read the #privacy-policy (on the right-hand side).

In short:
  • Since the beginning of the Chromium project until today, there is no binary of stable Chromium, shared by the official Chromium team.
  • The official website is development oriented. Users are invited to download Google Chrome.
  • The official download page gives to users only ZIP archives of development builds (also known as "snapshot", "nightly", "vanilla" or "raw" builds) which can be very unstable. Users are invited to download Google's Chrome Canary.
  • This site gives to users a choice of builds: development (also on its simplest download page), stable and portable builds.

All downloads are only from reliable sources:

1. Project

Chromium exists since 2008. It is the free and open-source project (#features) behind the famous Google Chrome browser. There are many advantages for an enterprise to work on an open-source project. Intrinsically, Chromium is a Google project maintained by many authors (developers, engineers, graphic designers, security researchers...) from Google, Adobe, Amazon, Cloudflare, Facebook, Hewlett-Packard, IBM, Igalia, Intel, Logitech, Microsoft, Mozilla, Nvidia, Opera, Samsung, Vivaldi, Yandex... and external contributors (Official graph).

Chromium is not only a web browser. It is a blend of different important open-source projects:
  • ANGLE (Graphics engine abstraction layer)
  • Blink (Rendering/layout engine)
  • Native Client (Sandbox for running native code)
  • PDFium (PDF generation and rendering library)
  • Sandbox (Security mechanism for separating running programs)
  • Skia (Graphics library)
  • V8 (JavaScript engine)
  • and others...

One or more projects are used in Chromium browser (obviously!) and other software/service like Google Chrome, Googlebot Evergreen, Bingbot Evergreen, Mozilla Firefox (ANGLE, Skia, Google Safe browsing), Opera, Vivaldi, Microsoft Edge (Search "chromium" at Microsoft Third Party Disclosures. Official PDF presentation), Skype, Spotify, Steam, Minecraft, TeamViewer, WhatsApp, Twitch, Android WebView, Microsoft Visual Studio Code, Adobe Acrobat, Electron, CEF, QtWebEngine...

Chromium is not fully designed by Google! However, as a primary investor, Google gives a consistent guidance and provides all free tools and services related to this project.

2. Stable Chromium version

Officially, Chromium does not have a stable release. The official developers (aka The Chromium Authors) do not release it to end users. So it is continually in development. Google Chrome is the stable release... but is not open-source.

Chromium is the project then Google Chrome is the product.

In fact, Chromium has a stable version! ^^
Chromium being open-source (#source-code), anybody can compile it. It is reproductible. You should be a developer to do this. Just get the current stable version (88.0.4324.96) from the official Git repository and compile it!
For example, the current stable version on #linux is 88.0.4324.96. In this version, there are 96 patches which correct many issues (bugs, feature requests, enhancements...).

All stable versions of Chromium on #windows, #mac, #linux... are always made by third-party developers.

The stable version of Chromium is compiled by:

3. Development

The development builds (also known as "snapshot", "nightly", "vanilla" or "raw" builds) are built automatically several times a day by the Chromium Buildbot (buildbot console) and made available as binary code releases.

Snapshot

Once a snapshot has been built, it is placed in the chromium-browser-snapshots root directory of Google Cloud Storage and is automatically tested. This build is really just development tool for checking whether issues are fixed in the latest Chromium code. It can be buggy and unstable. They are downloadable on the official site, my alternative webpage and this site (Check The Chromium Authors tag).

LKGR

If that snapshot build successfully passes the automated tests, it is considered as a good build (known as LKGR meaning "Last Known Good Revision") and can become potentially a stable build. For info, LKGR builds were stored in the chromium-browser-continuous root directory until Friday, 18 Mar 2016. The Chromium team has removed few LKGR builders (407399, 576253 and chromium-dev) but other ones still work (latest commit). Finally, there is no LKGR binary shared by the Chromium team... but any developer can re-compile it! ^^

Stable

A stable build is a development build tested by the Buildbot then improved by the Chromium team and all contributors.

4. Conclusion

Note this website and the Chromium builds are made and shared by volunteers (devoted developers), freely, in their spare time. There is absolutely no business, no revenue (#privacy-policy). We are neither Google nor a corporation. So please, respect our work. Officially, the #stable-chromium-version does not exist at all. We need time to re-compile Chromium. If you cannot wait for the latest version, prefer to use a development version (download page) or compile Chromium yourself (#source-code) or use other #browsers.

Features

Chromium vs Google Chrome.

Chromium browser has:
Why I used the "similar" word, here?
I cannot certify that it is "same/identical" as Google Chome because Chrome is a closed-source software.

Some developers maintain #chromium-forks that offer more features and enhancements. Thanks a lot for developers! ;)

Secure Preferences

Chromium has "Secure Preferences" feature which protect user data against #malware. On Windows, the user profile is encrypted based on the machine SID. So extensions, certificates and passwords are not portable. It works for Chromium and all #chromium-forks like Google Chrome, Microsoft Edge, Opera, Vivaldi, Brave, ungoogled-chromium... (except Cent Browser which is closed-source and therefore can be easily corrupted)

Info relative to this feature:
How to migrate user data from one computer to another?
The simple way to migrate your data is to synchronize them.
For info, you can also use free services like floccus, xBrowserSync.

Also, to export/import data manually:
There are unstable ways too:

Google API keys

To use Google services (Sync, Translate, Contacts, Hotword...), Chromium needs Google API keys.

Chromium can display a top message if the Google API keys are needed for Google services:
Google API keys are missing. Some functionality of Chromium will be disabled. Learn More
How to create your own Google API keys?
With your own Google API keys, many Google services (Sync, Translate, Contacts, Hotword...) will work. Follow the official API Keys page to get them. Other info at Github Gist. Then set three environment variables.

On Windows

Launch Command Prompt (cmd.exe) and enter the following commands:
setx GOOGLE_API_KEY yourkey
setx GOOGLE_DEFAULT_CLIENT_ID yourclientid
setx GOOGLE_DEFAULT_CLIENT_SECRET yourclientsecret
(setx = set environment variables permanently)

On macOS

This tutorial was written by Aargl on december 7, 2018 (#comment-4078). Thanks to him. There are 2 methods:

1. Method with ChromiumSyncEnabler

ChromiumSyncEnabler (Archive: ZIP)
  • Put Chromium_template and ChromiumSyncEnabler.py at the root of the current user (~/)
  • Put Chromium.app in ~/Applications
  • In Terminal, type: python /Users/your_user_name/ChromiumSyncEnabler.py
  • Enter your API keys

N.B.: if you want to activate for all users, do the same procedure putting the files respectively in / and /Applications (I haven't tried, but I can't see why it wouldn't work...)

2. Method with a plist file

Creation of a ~/Library/LaunchAgents/setenv.ChromiumSync.plist containing: <?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "https://www.apple.com/DTDs/PropertyList-1.0.dtd ">
<plist version="1.0">
   <dict>
      <key>Label</key>
      <string>setenv.ChromiumSync</string>
      <key>ProgramArguments</key>
      <array>
         <string>/bin/launchctl</string>
         <string>setenv</string>
         <string>GOOGLE_API_KEY</string>
         <string>your_key</string>
         <string>/bin/launchctl</string>
         <string>setenv</string>
         <string>GOOGLE_DEFAULT_CLIENT_ID</string>
         <string>your_key</string>
         <string>/bin/launchctl</string>
         <string>setenv</string>
         <string>GOOGLE_DEFAULT_CLIENT_SECRET</string>
         <string>your_key</string>
      </array>
      <key>RunAtLoad</key>
      <true/>
   </dict>
</plist>
(with "your_key" being the corresponding Google API key)

Of course, you can name the LaunchAgent setenv.ChromiumSync or anything you want.
  • This is perfectly working in 10.11
  • In 10.9, you must create 3 separate LaunchAgent files instead (one for each key)
  • I couldn't test more recent OSes, but I think it should work as in 10.11

The choice between method 1 or 2 depends on wether you want to enter your API keys each time or not... ;-)

On Linux

export GOOGLE_API_KEY yourkey
export GOOGLE_DEFAULT_CLIENT_ID yourclientid
export GOOGLE_DEFAULT_CLIENT_SECRET yourclientsecret

API keys

API keys assigned to Debian (source) GOOGLE_API_KEY "AIzaSyCkfPOPZXDKNn8hhgu3JrA62wIgC93d44k"
GOOGLE_DEFAULT_CLIENT_ID "811574891467.apps.googleusercontent.com"
GOOGLE_DEFAULT_CLIENT_SECRET "kdloedMFGdGla2P1zacGjAQh"

API keys assigned to Arch Linux (source): GOOGLE_API_KEY "AIzaSyDwr302FpOSkGRpLlUpPThNTDPbXcIn_FM"
GOOGLE_DEFAULT_CLIENT_ID "413772536636.apps.googleusercontent.com"
GOOGLE_DEFAULT_CLIENT_SECRET "0ZChLK6AxeA3Isu96MkwqDR4"

API keys assigned to openSUSE (source): GOOGLE_API_KEY "AIzaSyD1hTe85_a14kr1Ks8T3Ce75rvbR1_Dx7Q"
GOOGLE_DEFAULT_CLIENT_ID "4139804441.apps.googleusercontent.com"
GOOGLE_DEFAULT_CLIENT_SECRET "KDTRKEZk2jwT_7CDpcmMA--P"
How to disable Google API keys?
Without Google API keys, many Google services (Sync, Translate, Contacts, Hotword...) will not work.

On Windows

Launch Command Prompt (cmd.exe) and enter the following commands:
setx GOOGLE_API_KEY "false"
setx GOOGLE_DEFAULT_CLIENT_ID "false"
setx GOOGLE_DEFAULT_CLIENT_SECRET "false"
(setx = set environment variables permanently)

Now launch Chromium.

Widevine plugin

Widevine is a closed-source Google plugin to play DRM content (= protected audio/video files) for web browsers.

Chromium does not support Widevine natively. Note that Chromium developers and most of Chromium users do not use this Google plugin at all. We do not bundle/share it. Other people tried to obtain a licence from Google for an open-source project and finally did not get it (Archive: 1). However on this website, the widevine support is enabled on the stable versions (These versions are compiled with the GN argument: enable_widevine = true). So you need to install the Widevine plugin yourself to play DRM content.

In Chromium and Google Chrome, you can check the Widevine support at chrome://components → "Widevine Content Decryption Module" → The number must be different than 0.0.0.0 (screenshot)

Websites to freely test Widevine:
How to install the Widevine plugin?
  1. Make sure you have a Chromium version with enabled support of widevine and codecs (standard audio/video codecs + H.264/MP4).
  2. Get an offline installer of Google Chrome (mirror 1, mirror 2). Unzip its content (This is a 7-zip self-extracting archive) and grab its Widevine plugin. (screenshot)
  3. Follow the RobRich instructions at #comment-4955 (This link will show all comments of this site)

Flash plugin

Flash is a deprecated multimedia software platform. Adobe will be retire Flash at the end of 2020. Roadmap for Chromium. Roadmap for Firefox. Since 2015, the Flash #npapi plugin is discontinued. So, PepperFlash (PPAPI) is the unique plugin for Chromium. For info, PepperFlash is secure because it works in a sandbox. In short, it executes in its own process, separate from the browser's rendering engine.
How to quickly install the Flash plugin?
On Windows and macOS, Chomium find PepperFlash itself (= without #command-line-flags)

  1. Install PepperFlash (PPAPI) from Adobe website.
  2. Disable the checkbox in the chrome://settings/content/flash page. (screenshot)
  3. Test if animation works on the Flash Player versions page.
  4. Enjoy!
How to manually install the Flash plugin?
This is a full manual installation tutorial.
(If Google Chrome is already installed, go directly to "3. Add command-line flags"

1. Get PepperFlash (PPAPI)

This plugin is a non-free (proprietary) software developed by Adobe, and distributed bundled with Google Chrome. So get it from the official sources: Adobe or Google.

1.1 From Adobe

Different official ways:
After install, the plugin path will be:
- On a 64-bit #windows:
  • C:\Windows\system32\Macromed\Flash\pepflashplayer64_[version].dll (64-bit version)
  • C:\Windows\SysWOW64\Macromed\Flash\pepflashplayer32_[version].dll (32-bit version)
- On a 32-bit #windows:
  • C:\Windows\system32\Macromed\Flash\pepflashplayer32_[version].dll (32-bit version)

1.2 From Google Chrome

Canary channel:

1.3 From an unofficial source

(Use an online service to prevent #malware)
  1. Search "PepperFlash" or "PPAPI" at [RU] effect8.ru or patheticcockroach.com
  2. Download and open the .7z archive
  3. Get "pepflashplayer.dll" (rename it, if needed) and "manifest.json" files.

Optionally, get the Flash version number:
(If you want to see the correct version number on Chromium internal pages)
  • On all platforms, open the manifest.json text file in the PepperFlash folder.
  • On Windows, you can do a right-click → Properties → Details, on the .dll file

2. Change the plugin directory

If you want, prefer a short path for the plugin. It will be easier for the next step. ^^
Example on Windows: Put this .dll file in a path like C:\PepperFlash\ (Create the directory if needed)

3. Add command-line flags

Use these #command-line-flags:
  • --ppapi-flash-path=[plugin path]
  • --ppapi-flash-version=[plugin version]
  • And optionally --allow-outdated-plugins to disable browser notifications about outdated plugins

On #windows, create a Chromium shortcut. Then go to its properties and edit the target field: --ppapi-flash-path="C:\PepperFlash\pepflashplayer.dll" --ppapi-flash-version="32.0.0.465" --allow-outdated-plugins
On #mac, you will need to launch it from the command-line (in the Terminal): /Applications/Chromium.app/Contents/MacOS/Chromium --ppapi-flash-path=/Library/Internet\ Plug-Ins/PepperFlashPlayer/PepperFlashPlayer.plugin --ppapi-flash-version=32.0.0.465& The "&" at the end is not a typo. It is there to make sure Chromium is launched in a separate thread. Without the "&", Chromium would exit as soon as you quit the Terminal. Moreover, to simplify the Chromium launch, check How to create simple Mac apps from shell scripts (Archive: 1). Also see the #comment-566 and #comment-344.

4. Restart the browser

Relaunch it to apply changes.

5. Check the installation

6. Enjoy!

Now, even after browser updates, Chromium uses PepperFlash. ^^

NPAPI plugin

NPAPI is a deprecated API that allows browser extensions to be developed. Chromium 45.0.2416.0 (331982) is the last version which still has NPAPI plugin support enabled via chrome://flags or group policy registry. (sourceNPAPI deprecation)
How to still use a NPAPI plugin?
Few ways:
More info on site archives:

HTML5 audio/video

By default, Chromium does not support proprietary codecs (AAC, H.264/MP4) in the HTML <audio> and <video> elements.
How to use Chromium with all audio/video codecs?
Few ways:
  • On #windows and #mac, use builds with all-codecs or all-codecs+
  • or compile Chromium from #source-code with proprietary codecs, yourself.
  • or install an older version having ffmpegsumo file (Ex: 333350, 333334, 333283, 333258...)
  • or choose other #browsers
  • On #linux, you can use Chromium with proprietary codecs (ex: FFmpeg under Ubuntu)

Before 4 June 2015, we used an alternative with the Google Chrome ffmpegsumo file and our Patch HTML5 Media extension. More info on site archives:
Note about the H.265/HEVC video codec
Chromium does (and will) not natively support the H.265/HEVC codec. (official source)

Check HTML5 audio/video support at https://tools.woolyss.com/html5-audio-video-tester/

If there is a video issue, disable hardware acceleration (see #browser-crash).

Advanced

1. Internal pages

To access to all internal pages, use chrome://about. Copy and paste this special URL directly into the address bar (omnibox). Obviously, this special URL works only in Chromium and Google Chrome. Note: About configuration settings, there is nothing similar to Firefox's about:config in Chromium.

Few internal pages:
About browser plugins
Since version 57, the chrome://plugins page no longer exists. (official source)

Info:

2. Keyboard shortcuts

To use keyboard shortcuts (on Windows, Mac and Linux), check this full list of official shortcuts... and this one if you are developer. Most of the shortcuts are similar to IE, Firefox or any other browser.

3. Command-line flags

There are command-line flags (or "switches") that Chromium accept in order to enable particular features or modify otherwise default functionality. Note flags often contain experimental or obsolete code, so they tend not to stick around for long.
How to start Chromium directly in incognito (or private) mode, on Windows?
Add the "--incognito" flag at the end of the Chromium shortcut and restart the browser. (screenshot)
"C:\{...}\Chromium\Application\chrome.exe" --incognito

4. User data directory

About your profile (history, bookmarks...), it is important to know where is stored your user data.
How to change the user data directory?
Add the "--user-data-dir" flag at the end of the Chromium shortcut and restart the browser. (screenshot)
"C:\{...}\Chromium\Application\chrome.exe" --user-data-dir=..\my-profile-path

5. External extension installation

How to install an external browser add-on?
If you wish to install extensions directly instead of just downloading the .crx source file, you must:
  1. Change the flag chrome://flags/#extension-mime-request-handling to "Always prompt for install".
  2. Click on the link of the .crx file you want to install

Download the .crx source file of any extension directly from the Chrome Web Store via Get CRX or via a site like Chrome Extension Downloader, ungoogled-extension, CRX Extractor, Crx4Chrome. (For info, you can see the source code before to download the extension: CRX Viewer)
  1. Go to chrome://extensions
  2. Drag and drop the .crx file on chrome://extensions

If it does not work...
  1. Add the "--enable-easy-off-store-extension-install" flag at the end of the Chromium shortcut and restart the browser. (screenshot)
  2. Go to chrome://extensions
  3. Drag and drop the .crx file on chrome://extensions

If it still does not work...
  1. Unzip the .crx file
  2. Go to chrome://extensions
  3. Drag and drop the unzipped folder on the page... or click on Developer mode (Toggle in top right) then Load unpacked extension... (screenshot)

About updates:
  • You have to update manually
  • You can update when you want! ^^
  • If ever a new version sucks, just re-install the previous one

6. Source code

Before all, check the official guide for developers.

Official links to easily get or see the full Chromium source code:
Interesting info:

7. Older version

Never update your browser with a very old version. It even does not start.

To downgrade Chromium installed with the Installer (.exe):
  1. Open Chromium and check its actual version at chrome://version
  2. Close Chromium.
  3. Uninstall Chromium WITHOUT to delete your #user-data-directory. It is an option of its uninstaller. (screenshot)
  4. Get the Installer (.exe) of an older version (from the → download/ page or Snapshots repository about "official" builds)
  5. Execute it to install Chromium.
  6. Open Chromium and check the new installed version at chrome://version

8. Browser crash

You have encountered a browser crash or issue :/

Few ways to help you:

Also you can use #command-line-flags: --disable-gpu, --disable-accelerated-video-decode...

8. Browser benchmark

To test performances of the browser, do differents benchmarks.
Except as otherwise noted, for the result, a higher number is better.

Free websites without registration:
  • ARES-6 (Various tests using the newest web standards and features)
  • Basemark (Various tests using the newest web standards and features)
  • JetStream (JavaScript benchmark developed by Apple)
  • Kraken (JavaScript benchmark developed by Mozilla • Result: A lower number is better)
  • MotionMark (Graphics benchmark developed by the WebKit team)
  • Octane (JavaScript benchmark developed by Google)
  • Speedometer (Performance benchmark that repeats the same actions using DOM APIs)
  • WebXPRT (HTML5 and JavaScript test developed by benchmark maker Principled Technologies)

Browsers

1. Chromium forks

In simple words, a fork of Chromium means Chromium engine is used to create another web browser.

Proprietary browsers:
(developed by official contributors of the Chromium #project)
I do not recommend:
Why not recommended?
Because all of these browsers are closed-source, outdated, based on Chromium like Google Chrome... and most of the features they remove don't even exist in Chromium, in the first place. Control your personal info and #privacy yourself ^^

Colin (InsanityBit) explains this very well at "SRWare Iron Browser – A private alternative to Chrome?" (2012 • Archives: 1, 2)

Note if a new browser with "better privacy" than Google Chrome is based on Chromium and is fully open-source, it should be ok for me. But... Google is famous. Its privacy policy and marketing strategy are well known. So you have to ask you some questions. Do you trust in an unknown team more than Google? Is an outdated Chromium fork?
Few free and open-source Chromium-based browsers:

2. Other open-source "non-Chromium-based" browsers

Privacy

For a better privacy protection, use open-source #browsers like Chromium, Firefox. Do not forget: It is open-source does not mean it is secure and respects user privacy. Moreover, security ≠ privacy ≠ anonymity. If your browser is fully "open-source", it means that somebody with the capability can review the #source-code. It is easier for developers to find malicious code with versioning tools like Git or SVN. (Ex: Chromium downloads a Chrome extension as a binary without source code → corrected 7 days after the report). Only an open-source code allows such defense. This is better for secure browsing and user privacy. The security of Chromium is very solid. While I recommend ungoogled-chromium, Bromite and Firefox (cf. about:config/user.js settings, containers system, better content-filtering, easier way to stop browser automatic connections, support of a self-hosted Firefox Sync server) as the most reliable browsers for privacy enthusiasts in a standard web browsing, Chromium is probably a reasonable alternative for everyday web browsing.

My way for a standard web-browsing (but do as you like ^^):
  1. Modify your #hosts-file to stop "natively" domains who serve ads, spyware and malware
  2. Use a VPN with strong encryption for your whole OS or router to bypass many restrictions on Internet. Note you are not anonymous behind a VPN service (cf. Browser fingerprint, Server-side tagging...) (It is better than browser VPN/proxy #extensions)
  3. Use an up-to-date web browser
  4. Change few #browser-settings
  5. Install few #extensions

How to really be anonymous on the Web?
The anonymization solutions are especially necessary for the exercise of freedoms (ex: for journalist, political opponent in certain countries, researcher, whistleblower...). These solutions are obviously very used by hackers too. Personally, I think most people cannot be anonymous on the Web even using a VPN, proxy or TOR network. It is a myth that you cannot be tracked online. If you exist, you are findable, especially if you use multiple devices and websites. There are a lot of technologies to identify a user and get its data. Check the #guides and #tests for more information.

But it is possible to really be anonymous on the Web if your respect all security rules. The book "The Art of Invisibility" written in 2017 by Kevin D. Mitnick will convince you. In a few words, do not trust proprietary software/services, third-party VPN service providers (VPN Leaks, 'no log' VPN providers..., VPN hacked...) and the cryptocurrency (like Bitcoin).
  1. Buy a new computer (like a used computer) with cash, from an unknown person.
  2. Then remove the internal HDD (or format it). You will not use it. Prefer an external USB flash/SSD drive.
  3. Use Tails, Whonix, Qubes OS or a similar live Linux distribution. These ones uses the Tor network (Note Tor is often attacked).
  4. Change the MAC address.
  5. Connect to a public WiFi connection.
  6. Do not change settings or add extensions on Tor Browser. It will prevent your Browser fingerprint.
  7. Never login to a site/service for which you are already known.
  8. SearX and .onion addresses are welcome.
  9. Here we go!
Do you know...
Sure you can protect your privacy against tracking and profiling tools but it is really painful because these tracking tools are everywhere today: on Internet (website, app...), at home (computer, phone, router, smart TV, smart home speaker, smart bulb, smart grid...), in your car (GPS system, connected car...), in the street (video surveillance camera...), at your ISP and elsewhere. You can find them in hardware (firmware) and software (operating system, app, website, extension...).

Do you know in all computers (excepted RISC-V and Libreboot) there is an exploit-friendly firmware that user has no access?
Ex: in Intel processors, in AMD processors, in Raspberry Pi (proprietary Broadcom processor).

Do you know you are readily recognizable if you install browser extensions like an ad-blocker? It means, if you install browser extensions, your Browser fingerprint is unique. So you are unique on the Web.
Ex: browserleaks::proxy, Browser Fingerprint

Do you know there are probably untrusted certificates on your computer?
Ex: Apple, Google, Microsoft and Mozilla..., Dell..., Google..., Microsoft..., Lenovo..., Surveillance firm...

Do you know it is possible to follow a user behind Tor browser?
Ex: Advanced Tor browser fingerprinting, Browser Fingerprinting, Tor and its discontents, with CSS (noscript-tracking.go, CrookedStyleSheets), with extension fingerprinting or with a zero-day exploit!...

About the "No log" mention of a VPN, do you know the jurisdiction of the country where the VPN server is located has authority on the jurisdiction of the country where the VPN provider is located?
Ex: Choose a VPN provider from United Kingdom and connect to a French VPN server. There are no log in United Kingdom. Ok, but this is not the problem! The VPN server is in France and there will be logs in France. This is the law. [FR] Minimal logs lifetime in France: 360 days (Source: "Article 3"). [FR] Minimal logs lifetime in Europe: 14 days. So be careful when your VPN provider and its VPN server are located in countries from the Five Eyes or Nine Eyes.

1. Browser update

The reason for updating to the latest version is security. As security threats are found, they are fixed. Using an old version expose user to a number of security holes and privacy issues. Browsers are far more subject to hacking than other software.

2. Browser settings

Adjust all settings and advanced settings in chrome://settings:

3. Hosts file

Modify your hosts file to prevent your OS from connecting to domains who serve ads, spyware and malware. This will increase your OS security and save bandwidth.

Note:

4. DNS services

By default you are using the DNS servers of your ISP but you do not have to stick with them. Before to choose one, compare DNS performance. Free alternative Internet DNS services for personal use:
Note:

5. Web search engines

Note: Few #extensions exist to protect user privacy on search engines.

Search engines

Search engines index the content of web pages by running an algorithm on a web crawler.

Metasearch engine

Metasearch engines use another search engine's data to produce its own results from the Internet.
If you are a web developer, develop your own metasearch engine yourself ^^

6. Extensions

Note:
Priority to open-source (no code obfuscation) extensions for Chromium and Firefox:

Block ads, trackers, scripts and popups

uBlock Origin + uBO-Extra

Force to use secure connection of websites (https://)

HTTPS Everywhere

Stop link redirection in Google, DuckDuckGo and Yandex search pages

Google search link fix

Control the HTTP Referer on a per-site basis

Referer Control

Prevent canvas fingerprint

Canvas Blocker (Fingerprint protect)

Emule locally CDN

Decentraleyes

Prevent WebRTC IP leak

WebRTC Leak Prevent

Prevent CSS Exfil attack

CSS Exfil Protection

Unblock websites with a browser VPN/proxy

Browsec
  • Download: store, amo
  • Alternatives: anonymoX, HidemanVPN, TunnelloVPN, TouchVPN, Hotspot Shield
  • My advice: Prefer to pay for a safe and secure VPN provider protecting your whole OS ; or use a free VPN service without registration. Do not use Hola!, ZenMate or Betternet in their free version. Hola! is a botnet. Betternet shares/sells user data to third-parties. In its free version, ZenMate needs a registration.

Malware

Your antivirus has detected a malicious software in Chromium files.

False positive?

You have downloaded Chromium from a reliable source (#notes) and maybe also used open-source #updaters. In this case, it is surely a false positive. The detection is generic (heuristic). There is absolutely no backdoor or other malware inside Chromium. Remember that the full #source-code is available. You will get a similar result if you compile Chromium yourself.

Note a specific thing about Chromium browser:
  1. Chromium has no digital signature (unlike Google Chrome). It is not signed because is open source and not "owned" per se by any one particular developer or organization. Moreover, a certificate is not free for developers (Example, Apple Developer Program).
  2. Antivirus use generic detection and database of malware signatures.
  3. VirusTotal which aggregates many antivirus is a Google service using its Trusted Source project to limit false positives for software like Google Chrome (because it is digitally signed), not for Chromium.
  4. So, unsigned Chromium + any antivirus or VirusTotal service = More chance to get an antivirus alert.

False positive reports known for few years ago:

Authentic malware?

Yes. Obviously, it is also possible.
  • The common entry methods for Chromium virus are freeware downloads as bundled software (bundleware) and spam e-mails. It means Chromium has been silently installed via another software. Do not forget Chromium is free and open-source. So malware writers use Chromium to push malicious code on to your system. Remove this "fake" or suspicious Chromium web browser (like BeagleBrowser, BoBrowser, BrowserAir, Chedot, eFast Browser, Fusion Browser, Mustang Browser, MyBrowser, Olcinium Browser, Palikan, Qword Browser, Torch, Tortuga Browser...).
  • The other way is about a compromised Chromium repository on a reliable source (#notes).

If you find an issue:
  • Contact your anti-virus or anti-malware support
  • Report it on the official Chromium supports. For links, see my #comment-1 below.

Chromium updaters

To update Chromium automatically.

As always, never install a closed-source software especially if you have never heard it before! GitHub and its Gist service are good places to find good stuff. So, try these free and open-source Chromium updaters:

Updaters on Windows

Updaters on macOS

Discontinued updaters


Thanks a lot for all developers!
I do not support these tools. Please, contact the developers for thanks, issue, help...

@Hibbiki
Hi. Thank you for the windows quick update...
Regards. :)
Anon6434
Version 88.0.4324.96 for Win64 works fine.

Thanx @Hibbiki for update!
@Hibbiki
Thanks for the V88. But, a little bit less fast than V87. Thanks anyway.
I am updating my GitHub listings so I can keep a little better track of the builds.

Basically I am appending the SIMD requirement to the build header, plus I have added an AVX build for Linux.

Current builds:

https://github.com/RobRich999/Chromium_Clang/releases/tag/v89.0.4387.0-r842692-win64-avx2

https://github.com/RobRich999/Chromium_Clang/releases/tag/v90.0.4394.0-r844986-win64-avx

https://github.com/RobRich999/Chromium_Clang/releases/tag/v90.0.4394.0-r844986-win64-sse3

https://github.com/RobRich999/Chromium_Clang/releases/tag/v90.0.4394.0-r844987-linux64-deb-avx

https://github.com/RobRich999/Chromium_Clang/releases/tag/v90.0.4394.0-r844987-linux64-deb-sse3

Win32 will be like the following when released, probably Thursday:

https://github.com/RobRich999/Chromium_Clang/releases/tag/v90.0.4394.0-r844986-win32-sse3

----------------

Win64 AVX2 building is behind slightly due to that particular system being offline for hardware repairs. Hoping to have it fixed by weekend.

----------------

@Jerry Sending ya' an email about the changes. TIA!
@Hibbiki
Sorry about my comment above. New measurements: equally fast. Thanks again for the excellent work.
@RobRich, v90.0.4394.0-r844986-win64-avx crashes on youtube and twitch
Error code: STATUS_ACCESS_VIOLATION
@Daigo How about the SSE3 build? Thanks!
Anon6440
@marmaduke
Thank you for the up-to-date, stable, Mac build!!
@RobRich, sse3 also crashes.
@Daigo Thanks. Rolling new builds right now.
Give this a try:

https://github.com/RobRich999/Chromium_Clang/releases/tag/v90.0.4396.0-r845617-win64-avx

YT and Tw working here during a quick test.

Please let me know if there are any significant performance regressions.

Win64 SSE3 currently building.
Anon6444
@Hibbiki

A thank you from one of your 32-bit users.
@RobRich, 845617-win64-avx works fine, crashes are gone. And I don't see any noticeable performance hit. Thanks ;)
Anon6447
Thanks for the Mac build Marmaduke, is ungoogled coming soon?
Anon6448
32-bit [ungoogled]chromium matters!
Anon6449
@Anon6448

You could build it yourself in the time it takes to wait for someone else :)
@RobRich

Hello,
For me v90.0.4396.0-r845617-win64-avx, Hat's Off !

Thks
@Daigo+Luc77600 Thanks!

I rolled back to a subset of my optimizations. Now I get to find which specific optimization is the underlying issue.
Quick FYI for Mamaduke and any others using Polly when building on Linux. As of a recent LLVM revision, apparently Polly is no longer working via LLD ldflags when using ThinLTO. While it *might* not be as optimal, you still can run Polly early via Clang cflags for now if desired. I suspect that is what I will be doing until whatever the cause is resolved.

Think I might have found a responsible commit. Having to rebuild its parent LLVM checkout to verify. It could take awhile to resolve at the project level assuming the suspect commit is responsible.
Well, that was not the right commit. Anyway. Maybe poke at it more later.
^Actually it appears I could be wrong. o.0

The "issue" is not probably an issue at all. It looks like only certain build targets now qualify for LTO optimization above LTO=0 to speed build times.

Take a look here:

https://source.chromium.org/search?q=//build/config/compiler:thinlto_optimize_max&sq=&ss=chromium

LTO=0 is basically more or less just multi-threading linking. LTO=2 or above invokes levels of actual link-time optimizations. BTW, YMMV on what worthwhile optimizations LTO=1 does.

Anyway, IIRC, I recommended trying something like the above a long time ago in an ongoing dev discussion regarding build times.

I will have to redo placement and invocation of some of my extra optimizations as a result.
Clang is invoking LLD linking via the clang++ -fuse-ld=lld option for building Chromium on Linux. Yay?

On Windows ninja justs call LLD directly. I never really looked into it on Linux, but I suspect it did the same there until recently. ??

Reason? Trying to pass "-Wl,-mllvm,-polly" via a LLD ldflag when using LTO no longer works. Sigh. Of note Polly is not core to LLVM.

However an option core to the LLVM internals like "-Wl,-mllvm,-enable-local-reassign" apparently will pass through the fuse.

TLDR? Run Polly at its early position in Clang when building on Linux for now.
BTW, here is the Chromium commit for those curious:

https://chromium.googlesource.com/chromium/src/+/1cda6e7869534d75defd1b3a86cbdd38e562f3fd

Build times on the dev's system do look considerably better according to the commit.

ThinLTO caching should (or might?) be working without file leakage on Windows, too. Details here:

https://bugs.chromium.org/p/chromium/issues/detail?id=871962
https://reviews.llvm.org/D94962

My setting of link-time code generation to O3 for the select targets is just a matter of a different code placement in the build config. No big deal there.

I might have to break up parts of my Polly config to correspond to the two LTO optimization levels.

For example, running stripmining on the LTO O0 targets probably is a waste of time due to a lack of autovectorization. I might try -polly-vectorizer=polly instead there, assuming Polly's own vectorizer no longer crashes on Chromium code, along with maybe the Polly inliner since there is no link time optimization to do LTO inlining pass.

Conversely, I could continue with the preferred -polly-vectorizer=stripmine for LTO O3 to let LLVM deal with autovec there.

Yeah, potentially lots of "my mileage may vary" (MMMV?) stuff of course. I will try to have something out in the next day or two. Likely a Linux build first since that is where I am currently poking at code.
Circling back to the recent sync inquiry.

"We won't remove the API from your key, but we'll limit the quota to the quota for development. It's true that this will make the keys unsuitable for production use."

Source: https://groups.google.com/a/chromium.org/g/embedder-dev/c/NXm7GIKTNTE/m/Qxcew5lfCAAJ

Chromium *builders* pushing public builds with google_default_client_id and google_default_client_secret enabled in the build arguments are most likely to hit the issue. Sync and perhaps other API features will stop working for those builds if/when rate limit quotas for the specific keys are met.

Chromium *users* obtaining their own API keys and setting them through local system environment variables are likely to be okay as I doubt you will hit the dev rate limit quota via personal use.

If anyone here likes using sync, I strongly suggest obtaining your own API keys.

Linux AVX proof-of-concept build:

https://github.com/RobRich999/Chromium_Clang/releases/tag/v90.0.4398.0-r846489-linu-deb-avx

Performance did take a slight but noticeable hit, though I only ran a subset of my usual optimizations to get a build done. Probably will have to redo some of the opts due to running Polly early during clang codegen now.

----------------

/depot_tools/chromium/src/build/config/compiler/BUILD.gn

Add the Polly cflags. I used a subset for Polly for testing.

"-mllvm", "-polly",
"-mllvm", "-polly-detect-profitability-min-per-loop-insts=40",
"-mllvm", "-polly-enable-delicm=false",
"-mllvm", "-polly-ignore-aliasing",
"-mllvm", "-polly-invariant-load-hoisting",
"-mllvm", "-polly-position=early",
# "-Rpass-analysis=polly",

Then I added stripmining to the Linux (else) section under the "thinlto_optimize_max" target settings.

cflags = [ "-mllvm", "-polly-vectorizer=stripmine", ]

There is no use wasting build timefor stripmine prevectorization on the $$$thinlto_optimize_default" targets since LTO codegen at O0 does not perform autovectorization.

----------------

On a related tangent regarding Linux builds, I would suggest changing the Oz cflag under "optimize" to at least Os, too. Oz disables autovectorization in favor of further squishing binary size. O2 would actually be even better IMO if using PGO. ;)

----------------

I need to see if the Polly inliner will help anything for performance on Linux. I know it largely pulls in lots of redundant libc++ functions, which probably is not going to do much IMHO.

Admittedly it has been awhile since I have dealt with tweaking Polly at the early position during clang codegen. I was kind of hoping those days were behind us for ThinLTO building on Linux. Oh well.

----------------

While I have yet to test it, for Windows you should be able to invoke Polly to run during *LTO codegen* via ldflags as we have been doing for awhile now, then add a ldflag for stripemine to "thinlto_optimize_max" target settings.

Add the Polly ldflags:

"-mllvm:-polly",
"-mllvm:-polly-detect-profitability-min-per-loop-insts=40",
"-mllvm:-polly-ignore-aliasing",
"-mllvm:-polly-invariant-load-hoisting"
# "-mllvm:-pass-remarks-analysis=polly",

And under the Windows section of thinlto_optimize_max:

ldlags += [ "-mllvm:-polly-vectorizer=stripmine" ]
For consistency's sake I have moved -polly-vectorizer=stripmine back with the rest of the Polly cflags for building on Linux. The wasted cycles probably might add up to few minutes difference anyway.

@Jerry Feel free to combine, delete, or whatever all these recent random dev-related posts if desired. I have been more or less just venting about having to yet again sort through and update my optimization configuration. ;) I suppose posting here was better than yapping about it at the cats.... or probably more like the wall. lol
Thank you so very much for the latest Dev build of 90.0.4399.0 (846566) • Sunday, 24 Jan 2021.

Cheers!

It seems that you have updated your API according to the new Chromium’s variants of RobRich (SSE2, SSE3, AVX2, etc.)

However, it looks like only the official API has been updated, not the old V3 version.

Note that I am not migrating to your last version’s API because it no longer contains the ["download":] variable that I use …

If it's possible to easily update V3 too : I'll take.

Otherwise, I would change my API usage during the 3rd coming Corona lockdown to be compatible with the latest API in it actual version.

Thank you @Jerry !
