It does work correctly once you change useragent string though.

  I believe Firefox doesn't expose the audio device output picker, only letting you select a single output device (you can select one in the permission prompt, but changing it is difficult). Last time I looked into why Teams wasn't working right, that was the reason Firefox was still listed as unsupported, because this can easily miss up setups with conference call PCs hooked up to some fancy proprietary audio conferencing system.

  yes, I said it's standard webdev laziness. Many aeons ago I worked on webkit, and the first step for a great many site compatibility bugs is "does it work with a Firefox ua string". Because it is always easiest to just check ie/new-ie and then useragent gate everything else, that is what happens. Which is why we keep getting sites requiring chrome (new ie) or ie (old ie) - it doesn't matter if the site is broken due to reliance on chrome behavior vs spec, what matters is devs coding to a single browser and considering any deviation to be a bug in anything else.
