Currently x64 only because the x86 build failed to build. Will look into that for final release. Fix is css only so I didn't need to rebuild.

The portable builds are fully portable, the profile directory is inside the browser folder. It does not touch appdata at all.

Requirements to use the browser on a given OS: Vista: Service Pack 2 + KB971644 Platform Update 7 RTM/SP0 and later: Should just work.

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.

Cairo/GDI backend ignores system cleartype settings and causes crashes on older versions of Windows and crashes without e10s.

r3dfox specific changes on top of the previous v143.0b8 build: Fixed tab height increasing once there are enough of them for the overflow menus to appear.

Haven't tested on XP (OCAPI) nor have I extensively stability tested.

Please let me know what bugs or issues you encounter with it.
