Going fullscreen in youtube or netflix doesn't hide the taskbar

[reveluv]

Hello

Since yesterday when trying to watch a video fullscreen on a streaming site the windows taskbar pops up on top of the video and doesn't stay hidden like it should be. I tried disabling my extensions one by one to see if one of those causes the issue but it didn't make any difference.

Tried running nightly in troubleshooting mode and it worked, but after switching back to the original, the problem persists.

If you have any ideas or if someone else also has this problem, please respond.

Thank you

This should be fixed as of https://bugzilla.mozilla.org/show_bug.cgi?id=1952284.

If updating Nightly doesn't fix it, can you try running the test described in https://bugzilla.mozilla.org/show_bug.cgi?id=1952284#c3 and report — in that issue — what the behavior is for each value?
