Youtube video is black when in fullscreen
When playing any youtube video in full screen, all I get is a black screen. Issue does not appear in private mode, firefox developer build or chrome. Other sites ex. go pro media plays videos in full screen without any problems

Start Firefox in Troubleshoot Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration or if userChrome.css/userContent.css is causing the problem.
- switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Themes
- do NOT click the "Refresh Firefox" button on the Troubleshoot Mode start window

Thanks for your reply! Tried running it in troubleshoot mode with no luck. Currently have no extensions enabled and toolkit.legacyUserProfileCustomizations.stylesheets setting is set to false. The theme is set to System theme - auto
Also clearing cookies/cached content didn't do anything
