Often I turn on some video before going to sleep. Of course I can fall asleep during watching, so I've set Windows to go in Sleep mode after 5 minutes of idle. But problem is when video in full screen mode - it preventing Windows from going into Sleep mode. So I want to make Firefox exit full screen mode after HTML5 video ends playing.

Currently I didn't found any settings to do so (even in about:config), so please point me if such setting exist or if not - please make it available (at least as setting in about:config).

Hi  !

The first thing that came to mind was : 'Don't watch soporific videos before you go to bed .... '

But then I found this :

Any good  ?

Seperate issue : Your system details show that you need to update your Adobe Flash Player (which can cause problems), so would you please uninstall your current version and install the latest version, which is 28.0.0.137

Uninstaller : https://helpx.adobe.com/flash-player/kb/uninstall-flash-player-windows.html

Note : some 'extras' may be offered in the download.
