Comment 8 for bug 579674

I would find it simpler if you could access the sidebar/topbar in fullscreen mode. If I want to switch app from a fullscreen one, I have to either alt-tab to it (which exits fullscreen mode, since the fullscreen is for one app only) or to lose the fullscreen, and THEN change app.

It also means that users unfamiliar with the keyboard shortcut have no way to exit the fullscreen, as the menu becomes unaccessible during fullscreen.
