according to my testing with FF/TB on debian both showed issues
accessing to microphone and recommended visit a web page (in yellow
error) which is saying which browser i should use and its only showing
chrome & chromium.
On TORbrowser I can’t get to ask/have permission for camera and microphone, (it does not get the webpage in settings)
On Firefox it starts , permission is granted to both mic and camera, but nothing is shown: only thing that works is chat and hand rasing, not video, not mic, not screen sharing
