Hi
I tried to replicate the issue using windows10 and Ubuntu 18.04 and the latest Firefox Nightly release 73.0a1
but after i login with my office365 account and choose teams, it asks for login again and never enters, I think im missing teams access so i can´t double check it.

Can you please re-test with latest Firefox Nightly release? from here: https://nightly.mozilla.org/

If you still have the issue please create a new profile, you have the steps here:https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles?redirectlocale=en-US&redirectslug=Managing-profiles#w_starting-the-profile-manager

Lastly test if the issue is reproducible in safe mode, here is a link that can help you:

I use Teams almost everyday on Windows 10 and, apart not being able to call, I never noticed Firefox-related problems.
In last days, with the first releases of FF 97 Developer, Teams told me Firefox wasn't compatible, but today it works again (didn't try calls).
Sometimes I have this sort of problem on login https://docs.microsoft.com/it-it/microsoftteams/troubleshoot/teams-sign-in/sign-in-loop
This is NOT related to Firefox, infact I also face it on Chrome.

I've had this issue too, but I found out it only happens when darkreader changes the page to dark mode. I have a guess it is beacause it changes classes of the elements and/or javascript that interferes with some MSTeams magick.

Tentatively moving to WebRTC, not sure which components is should be but it's not Widget:gtk.
