Bugzilla

Yes it reproduces for me in both 144 (release) and 146 (nightly). Other than a camera preview added to the Firefox prompt in 143, the selection logic in the prompt remains the same.

To clarify: the problem only manifests when the user picks a different camera device from the one offered in the Firefox permission prompt, and does so from inside that prompt.

Here are the REPRO STEPS I use:
1. Ensure two cameras are connected
1. Clear any previous `Allowed ✖` or `Allowed Temporarily ✖` permissions for camera in the dropdown to the immediate left of the URL bar
1. Click "Meet Now" in Teams
1. In the Firefox permission prompt that appears, change the camera offered (A) to the OPPOSITE one (B), and hit Allow
1. The Teams lobby appears. If a self view does not appear, click the unmute button in the lobby UX) 

Expected result:
- Camera B is rendered in the lobby

Actual result:
- Firefox prompts for Camera A
- When allowed, Camera A appears
- User has to change camera from the web UX instead.

Note Firefox can be inconsistent in which camera it considers the default depending on when devices are plugged in. Just make sure whichever one it suggests you pick the opposite.
