People have asked for a 115 ESR build, and I figured to offer something over stock I would make it also support Vista.
Currently this is a beta for a few reasons:
1: The 32 bit build is built with --disable-sandbox. With the sandbox enabled it fails to open multiple processes which breaks the browser.
2: The 32 bit build doesn't start PGO. This could be Rust9x, since PGO on the 32 bit build has been funny ever since I started using it but idk.
3: Most of the r3dfox customizations options do nothing and I have no idea why. So it's hardcoded to be the default for now.
4: I have to hex edit out two calls for TryAcquireSRWLock functions, and I have no idea where they get called from to fix in code.
5: I forked this while the code is in a non-release state, 115.13.0 isn't released yet. I could probably revert back to 115.12.0, but I just wasn't thinking about it until typing this right now.
Otherwise, it seems to mostly work, no idea how well or how stable it is. Needs testing.
The portable builds are fully portable, the profile directory is inside the browser folder. It does not touch appdata at all.
Haven't tested on XP (OCAPI) nor have I extensively stability tested.
Please let me know what bugs or issues you encounter with it.
