Description: while viewing videos on youtube, twitch, odysee (and possibly other sites with videos), the video player may suddenly stop playing, and after that, no video in firefox can be played. Restarting the browser makes this issue disappear for a while, but i'd like a permanent solution.

What i've tried so far: Disabling uBlock Clearing cache and cookies Enabling/Disabling hardware acceleration Disabling proxy extension Disabling antivirus on PC.
