This revision fixes an issue with some non-personal files being left behind in the ProgramData directory.

Confirmed. Mozilla for some reason served the builder 85.0.2 instead of 91.0 for en-US only for no apparent reason. I've adjusted the building to use a different addressing system and am rebuilding.

Rev 3 fixes an issue with the Firefox Portable en-US package containing an older version of Firefox due to a glitch in Mozilla's old download link format. I've updated the builder to use the new format as they are in the process of retiring their ftp. addresses. My apologies for any inconvenience this mixup caused.

If you update to 91.0.1 today (or to rev 3 from before), it'll remove them on exit as they're specific to the portable install.
