I have been unable to watch youtube videos in Firefox for a few days now. They simply stop after irregular intervalls and if I resume playback manually the video lacks any kind of sound I've noticed the same problem on Floatplane today. Here's what I tried to resolve the issue. 1. Launch Firefox without any Addons. 2. Disable hardware acceleration. 3 Reinstall Firefox and delete all profiles except for the latest one using the profile manager. 4. Installed the latested Nightly Build of Firefox. Nothing helped. I've switched to annother browser for the time being. I hope this issue can be resolved
