Could you describe the situation in more detail. Do the player rectangles display an error message, or a loading animation, or are they blank? If the video seems to be loading, are the controls not working?

For example,YT videos has a spinning circle and then says if video fails to load try restarting your device. I've already done that and disabled hardware acceleration and all add-ons and still no video. All other sites have spinner showing loading but nothing. Yes I do see controls and on YT if I hover over timeline I see different stages of the video or thumbnails that should be playing.

I also can't play Video on some machines with Beta 85. It cannot be played even with the new profile, but it can be played by returning to Firefox 84.
