Firefox’s tracking protection is very aggressive and breaks some sites because it incorrectly thinks a first-party domain is actually a third-party one. For example, for some sites it thought the CDN at a separate domain was a third-party domain and blocked all the JS from loading. At work I’ve had to make a bunch of fixes to the disconnect.me list they use.
Do you have enhanced tracking protection on? Knowing Microsoft you might need to disable it for teams to work right
They told me in the UI to turn it off.
It could be the issue or OP didnt read the error message.
People don’t read error messages, even if they describe exactly what to do to fix the problem. :(
