Since a recent update to Firefox 105.0 on Xubuntu 20.04, I can't play youtube videos anymore.
The preview image loads, and when I click the play button the video plays for like 1-4 frames, then snaps back to pause.
I ran firefox again from the console and got the following error messages:
Playback = "k key".ERROR mp4parse] Found 2 nul bytes in "\0\0"
So, keeping "k" pressed, will play back the actual video. But basically without sound. Flickering.
A bit like a silent movie
[UPDATE]
Maybe I'm getting closer (Firefox WebDev log):

Still investigating what's going on here and how to fix it...
