Note: If you are upgrading from 127 or earlier, 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.
Notable bugs:
The 32 bit build is built with --disable-sandbox. With the sandbox enabled under Vista, the browser fails to open multiple processes which breaks the browser. The 64 bit build is fine. Considering Mypal68 globally disables the sandbox, I don't think it's that bad. If this really is a big issue then please pr a fix.
Changes on top of the previous 129.0-2 build:
DoH settings in preferences work again again because people wanted it to work before Mozilla fixed it.
Inactive window menu bar text is always black.
Haven't tested on XP (OCAPI) nor have I extensively 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.
