Bug Description

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.
