Firefox – Disable firefox fullscreen warning with html5 stuff


Whenever I go fullscreen in html5 things it puts a message at the top saying you're now in fullscreen, the problem is that this message totally stops you being able to do anything else until it disapears. So if I open a youtube video in fullscreen I can't pause it or do anything until I wait for the message to disapear. How can I disable the message totally?

This is the security feature, but yes it's annoying if you're on trusted site and the message popups every time you enter full screen.

Solution: enter about:config in address-bar, and search for full-screen-api.approval-required and set it to false

You're done!
