Version 97.1.0 broke full screen video on Samsung Galaxy S10 Lite. These problems don't occur in Chrome. 1. When I play a video full screen with the phone in landscape orientation the video doesn't take up the full height of the screen, so the video is smaller than it should be. 2. When I exit full screen mode and turn the phone back to portrait orientation the Android Navigation Bar is not present. So I'm stuck in Firefox and can't do anything else with my phone.
