Videos on firefox suddenly max volume

more options

When playing a video with Firefox the volume will suddenly jump to maximum. It does this with any video I play, regardless of source, and only Firefox is causing this problem. I tried the same variety of videos on Chrome, edge, and music from media player and none are having this issue.

Did you also check the volume setting for the plugin-container process?
