## Chromium fork for linux named [after radioactive element No. 90](https://en.wikipedia.org/wiki/Thorium). Windows/MacOS/RasPi/Other builds see below.
- Intended to behave like and have the featureset of Google Chrome, with differences/patches/enhancements listed below.
- Includes Widevine, All Codecs, Chrome Plugins, as well as thinLTO, CFlag, LDFlag, LLVM Loop, and PGO compiler optimizations. It is built with SSE4, AVX, and AES, so it won't launch on CPU's below 2nd gen Core or AMD FX, but benefits from Advanced Vector EXtensions. You can disable this and use regular SSE3 like Chromium and Chrome, or builds from Thorium special, some of which are SSE4. (See below.)
– I also build for Windows > [Thorium Win](https://github.com/Alex313031/Thorium-Win) You can also find SSE4 builds for Windows here.\
– AVX2 Builds for Windows and Linux > [Thorium AVX2](https://github.com/Alex313031/Thorium-AVX2) (source files for AVX2 are in that repo.) \
– MacOS (M1 and X64) and Raspberry Pi (arm64) Builds, as well as Special and Experimental builds, sometimes for other CPUs (read the Readme), are located at > [Thorium Special](https://github.com/Alex313031/Thorium-Special) You can also find builds for Piledriver/Steamroller/Excavator CPUS, Haswell CPUs, as well as SSE4 Linux builds. \
### FEATURES & DIFFERENCES BETWEEN CHROMIUM AND THORIUM <img src="https://github.com/Alex313031/Thorium/blob/main/logos/NEW/bulb_light.svg#gh-dark-mode-only"> <img src="https://github.com/Alex313031/Thorium/blob/main/logos/NEW/bulb_dark.svg#gh-light-mode-only">
> - Various compiler flags that improve performance and target AVX CPU's (read [PATCHES.md](https://github.com/Alex313031/Thorium/blob/main/PATCHES.md))
> - Patches from Debian including font rendering patch, VAAPI Patch, Intel HD support patch, native notifications patch, title bar patch, and... the VDPAU Patch!! (Rejoice Nvidia users)
> - Inclusion of <img src="https://github.com/Alex313031/Thorium/blob/main/logos/STAGING/pak.png" width="16"> pak (linux) and pak_mingw (windows), a utility for packing and unpacking the *.pak files in Thorium and any other Chromium based browser.
> - Includes installer patches and files to include ChromeDriver and content_shell (thorium_shell), with a .desktop file being provided for content_shell (named thorium-shell.desktop and shows in desktop environments as Thorium Content Shell). These are also included in the Windows releases, but it doesn't make a shorcut, although a .png and .ico is in the install directory for you to make your own shortcut with an icon. You can also run content_shell with the command thorium-shell (custom wrapper for it, located in /usr/bin/). You can run ChromeDriver at /usr/bin/chromedriver or chromedriver.exe onWwindows. Also, patches for abseil library and mini_installer when building with AVX on Windows.
> - Right clicking the launcher after install gives three additional desktop actions, one to open thorium-shell, another to open in Safe Mode which disables any flags one has set in chrome://flags until the next launch, and lastly to open in Dark Mode which appends the --force-dark-mode flag.
https://www.reddit.com/r/ChromiumBrowser/ is a subreddit I made for Thorium and general Chromium discussion and https://alex313031.blogspot.com/ is a blog I made relating to Thorium/ThoriumOS. \
I also build ChromiumOS (now called ThoriumOS) with Thorium, Codecs, Widevine, linux-firmware/modules, and extra packages at > https://github.com/Alex313031/ChromiumOS/
