Wow, you’re right. Teams is not fully supported. Apparently Video and Sharing in Meetings is limited. Didn’t know that. Well that sucks

I don’t know how many normal sites even have a problem with Firefox. I guess only some small, niche web apps, but otherwise most people would see no difference. Even if developers don’t explicitly test on Firefox, almost all features will still just work (at least for normie usage). Power users might encounter some challenges, as the post describes.

I use Firefox btw. (not Arch though)
