This morning, I needed to join a Teams meeting. After I'd clicked the link, I was asked if I would allow Microsoft to use my audio and video; I ticked "Allow". But, when I joined the meeting, I found that I could hear and be heard but I couldn't be seen; my video icon refused to react when I tried to get it open. It was only when I came in through Edge that I could be both heard and seen. Is there any way I can get into a Teams meeting through Firefox? (I have downloaded Teams on to my desk top.) Steve
