Firefox no longer able to play videos
I'm no longer able to play any kind of video in Firefox. Regardless of source - Netflix, Youtube, clips on twitter, whatever - I just get the loading circle.
All videos I've tried have been totally fine in Chrome and Edge, so it's not the source or the internet correction.
I've tried: - Running Firefox in safe mode (without extensions) - Clearing browser cache - Refreshing Firefox - Reinstalling Firefox - Disabling hardware acceleration
Any further suggestions? Firefox 93.0 on Windows 10 Enterprise, for the record.
