Controlling data sharing, visibility, and access permissions within Microsoft Teams
Hello jordan, my name is Farah and I'm an Independent Adviser. I can help you regarding this problem
Does this happens only when you start Teams? or is this a general issue with Firefox?
I suggest to reinstall Firefox at first, a download link can be found here:

Check Teams in other web browsers as well to see if it does work..
Feel free to ask back any questions and let us know how it goes.
Cheers!
Farah
