Hello, so when I watch youtube on FF my cpu usage goes up alot and the fans go nuts. I have a very capable i5, rtx3070 machine and this issue started just a couple of days ago. I have not done any changes or updates which could trigger this problem. The problem starts mainly when I Watch in full screen mode or have multiple non-fullscreen vids active. All other apps show no signs of problem. I can watch the exact same video in Edge, no fans/high cpu, VLC works fine, Chrome is OK, it's only in FF that the problem occurs. I have tried the following: 1.Reinstalling FF 2. Activating HW acceleration in FF and forcing it in Windows11 3. Theatre mode is off and all other YT settings are off. 4. Updated Nvidia and windows 5. FF is the latest version. 6. Disabled all my addons/plugins No clue what can cause this..
