I wonder if FaceTime is just looking at UA, or doing proper supported features check? Microsoft Teams supposedly are not working in Firefox because they use some old WebRTC standard. Apple should be building on new standards, right?
Looks like they’re using feature detection and Firefox is missing that feature
It would be nice if someday opensource would get some official recognition. Because right now, hoping that something will work is the only thing we can do, even for government websites and apps.
