Steps to reproduce: - Tap on the window.fullScreen = true button Notice how the browser is now in full screen mode, but there is no way to get out of it. Unless you tap on the window.fullScreen = false button. There should be a way from inside the browser to get out of full screen mode. With the element.mozRequestFullScreen method, the Android back button is used to get out of full screen, so I guess that should also be used for this case.

I thought Matt or Margaret fixed a similar sounding bug. Maybe it was part of the changes that Matt made for the Fullscreen add-on.

F11 works on desktop to get out of fullScreen mode. Makes sense that BACK on Android should do it too.

But this would leave you without a way to navigate back in history. If you enter fullscreen mode by toggling the preference, just toggle it again to exit. The "Full Screen" add-on provides a menu item if you want a way to do this in the UI: https://addons.mozilla.org/en-US/android/addon/full-screen-252573/

Sorry, I didn't realize it was possible to set this from content... We should either disallow that by default, or provide in-browser UI to reset it.
