Only the latest commit is relevant. Built only for x86_64. Didn't try for i686 and armv7h. I saw there were some changes from Arch Linux 32 for firefox 100.0, and Arch Linux ARM has also updated their package, but I didn't merge those changes.

BTW, there's 100.0.1 already, but as far as I could see, the diff with the contents of source tarball of 100.0 consisted only from some changes related to Netflix bugfixes and also something related to MacOS, so I didn't bother to built this newer release since these changes are not relevant to free software community anyway.
