When watching YouTube (or other HMTL5 video content) in Firefox the video's fullscreen mode does not work correctly. When I press the fullscreen button (usually to be found at the right-bottom) and Firefox switches to fullscreen mode my tab bar and url bar are still visible, but my bookmark bar is gone. When I return from fullscreen the bookmark bar does not reappear.

In Firefox 39 I was able to switch to Fullscreen (without any visible bar) and return from it (without losing any bar in the process) and didn't have any problems.

Do you have a solution for this problem or should I just wait for this bug to be fixed?

Start Firefox in Safe Mode {web Link} by holding down the <Shift>
(Mac Options) key, and then starting Firefox. Is the problem still there?
