Public bug reported:
After upgrading to 21.04 Firefox randomly becomes unresponsive without
freezing. If you have any video or audio files playing they will
continue but you cannot pause them or do anything with Firefox but quit
it. Keyboard shortcuts don't work either. It seems that html5 media
create this issue.
