FIX FIREFOX FULL SCREEN

R1_Toomany

is there anyway to stop firefox from exiting out of full screen when I hit escape on a youtube video after watching it in full screen? this use to never be a problem before now every time I watch a video in full screen and i hit escape the video exits and firefox exits out of full screen. is there any way i can keep firefox in full screen when i exit out of watching a full screen video. This happens with any method. hitting the full screen button on a video to get back to the reg size also takes firefox out of full screen

Is this problem with the Flash player plugin or with the built-in HTML5 video player? Usually you can tell which one is being used from the last item on the context menu (right-click or Ctrl+click the player).

so what would I do after that?

Either you can force YouTube to use Flash, as a temporary workaround, or... the problem will be fixed in about two months when Firefox 40 is released.
