Enabling this script and playing any video will cause a large part of the youtube video UI to become unresponsive. This includes:
Clicking on the video player to play/pause
Clicking on or dragging the progress bar
Clicking on any of the buttons on the bottom of the video player (mute, volume, settings, captions, etc) except for play/pause
Using any of the keyboard shortcuts (arrow keys, jkl, etc)
Using Librewolf (a Firefox fork) version 126.0.1, but this has been happening for a while - only just now narrowed it down to this specific userscript. Confirmed by disabling FF's own tracking protection and disabling all other extensions (private browsing window).
