I have to use Microsoft Teams for work. I use the web version with firefox. The audio portion works just fine and the video portion works too. But the screen-share function does not work. I can’t see anyone else’s screen when they share it.
Firefox always has a notice when I start up MS Teams (attached the image to this post). But when I click on the “Learn More” button, the bar just disappears without taking me anywhere new. So I’m unable to learn more. Does anyone know what plugin I need or where to download it? I’ve done a couple of searches and haven’t come up with anything helpful so I’m hoping someone can help me solve this problem.
- Do you perhaps have Resist Fingerprinting or Strict Enhanced Tracking Protection turned on? - I was never able to get videoconferencing sites working with any combination of those (on Linux), so I just use a vanilla Chrome instance just for videoconferencing. - Oh that’s interesting. I don’t use RFP but I do use Strict ETP. Maybe that is the issue? I think I’m just going to do this in a Windows VM and call it a day. 
 
- Likely some DRM or tracking crap. So this is a Microsoft Teams message, not Firefox. What OS do you use? - It’s not a Firefox Message? I use Fedora as my OS. - That is the question. Please send a complete screenshot. - This is a microsoft teams message. It’s the teams colour scheme and design. Firefox messages are grey and left-alligned:  - Ok so its likely bullshit 
 
 
 
 
- Is Firefox maybe blocking a popup when you click on “Learn more”? - Good thought; I had the same one. But it isn’t… I checked for that. 
 
- Have you tried changing the user agent to chrome to see if it works for you? - No, I haven’t done that yet. I know FF wasn’t officially supported before but I thought MS supports it now? - I would think May would try their best to shift you to edge instead. - Switch that user agent and see. - I’ll try it out. Thanks for the tip. 
 
 
 
- Best guess is standard MS buggery. - I had teams running on my phone, but removed it on account trying to improve my mental health. The other day I needed to use teams on the go, and I tried using firefox on android. No dice, browser not supported, why don’t you try our client? So I tried desktop mode, found out that I still had chrome installed, then tried opera and at last I even installed edge, and tried all in desktop mode as well. - I get that some functions may not work in rando mobile browsers, but teams noped out of every try. So guess who still isn’t accessible on teams. 
- You probably need to enable DRM content, it’s a setting in Firefox.
