Finally. Thought I was going crazy about the YouTube playback getting stuck all the time!
- I wonder if this will fix Twitch too, video playback in VODs seem to get stuck as well...
  
  Not sure. YouTube broke it on their own end -- and conveniently only for Firefox again. 🤔
  
  From what I read last week, basically they were sending chunks of the video stream in a completely invalid way. Essentially saying a new chunk of the video begins at an earlier frame than the last chunk ended.

Oh thoanks, now I'm happy.
