Here it is, as requested. I found out today that the problem only exists when I'm viewing a video from youtube. I tried videos on www.guardian.co.uk and the iPlayer on the www.bbc.co.uk site and they behave completely normally. There is no tab bar or navigation bar above the video.

Here is another hint about this problem. A second annoying "feature" of full-screen is that it wipes out the Bookmarks sidebar. When I return to normal view (not full-screen) the bookmark sidebar is gone and I have to reconfigure it via the View->Sidebar->Bookmarks menu. In today's Nightly the problem has now spread to the Guardian's videos although the BBC's iPlayer is still immune from this problem

Then switch to the Firefox Full-Screen Mode. Click the button and then on Fullscreen.

Been there. Done that. No help at all. The behaviour of the Bookmarks sidebar makes me suspect this is a definite bug of nightly.

When I go to F11 the screen expands but leaves the tabs and url space as two lines at the top of the screen. I have a screen shot of this.

How do I change things to make the full screen without these lines of unwanted information?

Hi dsiddens

You can right-click empty space on the Tab bar or Navigation Toolbar to open the toolbar context menu and set a tick on "Hide Toolbars".

Went to a desktop which showed tabs, and tried the right click. It wasn't until after I "excerised" the '+' in the upper right corner that the full screen became free of the unwanted bars.

So a big thank you for your prompt help on this!
