Hello, and thank you for the update. That indeed seems unrelated. I'd suggest looking for reports of similar issues on upstream's tracker https://bugzilla.mozilla.org to see if anyone else may have run into this, and if yes then add as much detail as you can in form of a comment, and if not then consider making a report there as well so as to bring the issue to the attention of Firefox developers. In either case, I'd appreciate it if you would please provide the bugzilla bug number here so we could add it to this bug's metadata.
Thanks again. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/2078059 Title: MS Teams screen sharing frequently stops working when accessing Teams from Firefox Status in firefox package in Ubuntu: New Bug description: Observed: I access Teams from Firefox and it works as far as I can tell, including live meetings. Occasionally though, when I try to share my screen (it is always a specific window I'm sharing), others in the meeting see that I'm sharing something, but they don't see the window. Firefox seems to work just fine in all other respects: browsing different web sites, Teams audio and video etc. Expected: Others in the meeting should always see the window that I share. Repeatability: Hard to say. I can have several meetings over a few days and screen sharing works fine. When it fails, it fails completely, i.e. it will not work, regardless of how many times I try. Workarounds: * use a different browser for Teams * restart Firefox Notes: I use suspend/resume on my machine a lot, so my browser works for days (with several windows open and dozens of tabs, typically), if relevant.
