I use FirefoxDeveloperEdition 40.0a2, with OSX 10.10.3. After I set a youtube video to full screen and then return to normal view, the toolbar ( Bookmarks ) is gone. Everything is still set the way it is supposed to ( display toolbar and so on ). After I restart firefox everything is back to normal. I removed all disabled all addons, but it did not change anything. Any Ideas how to solve this?

First I need to add that if I open a new window, the toolbar is displayed in that window, not in the old one. So a restart is not necessary after all.

Of course I tried to set the toolbar to view again. But as I said in my post all options are still set on view toolbar, it just isn't viewed.

I updated all plugins one at a time and tried again. The problem is still around.

I managed to narrow the problem down. As far as I can tell the problem only occurs on the youtube page, while using the HTML5 player. I installed YouTubeFlashPlayer an extension that forces youtube to use flashplayer instead of the HTML5 one. This solves the issue.

First: Please update your plugins to the latest version. Check to make sure you are up to date:

Second, please make sure that you report this to the developers at input.mozilla.org.

There was a work around in the past https://addons.mozilla.org/eN-US/fire.../old-lion-fullscreen/

Does the Bookmarks Toolbar reappear if you disable and re-enable this toolbar?

  • "3-bar" Firefox menu button > Customize > Show/Hide Toolbars
  • View > Toolbars
    Tap
  • Right-click empty toolbar area

Does the toolbar appear if you open a new window?
