After the latest update in playstore, every video i play in firefox is not in fullscreen. There is a 1 cm thick grey bar under every video. Was using nightly for a long time until this error started to appear. Then switched to the "normal" firefox. But after 1 month it started also with the latest playstore build. Any fix for this?
