So compiling the Rust compiler for AVX2 also makes the output require AVX2, who knew.
Previous description from v128.0:
Note: You will want to uninstall any old versions of r3dfox before upgrading to 128. This will not touch your browser profile or settings. If you do end up with a new profile or no settings, follow these steps. Go to about:profiles, select the previous profile (Usually default-default) as default, and restart the browser.
The portable builds are fully portable, the profile directory is inside the browser folder. It does not touch appdata at all.
Changes on top of the previous b128.0 build:
Browser is now compiled with custom built eRust 1.77.2 instead of 2024-02-04-nightly.
Mozilla made a few changes in the period between b128.0 and now, they don't seem of note.
Haven't tested on XP/Vista (extended kernel) nor have I stability tested. If you are using 7 RTM, you need to install the VC++ 2019/2022 redistributable, and copy the appropriate files from the r3dfox-7-RTM-fix.7z to the r3dfox installation directory, and it should work.
Please let me know what bugs or issues you encounter with it.
