When I switch YouTube video to fullscreen, this message pops up: 

 "youtube.com is now fullscreen. Exit fullscreen (Esc)"

after having seen this evil message ten thousand times, I think I understand that I can exit with Esc, and I don't need to be reminded again.

How can I disable this evil feature on Firefox 45 ?

I have tried setting 

 full-screen-api.approval-required to false
 full-screen-api.transition-duration.enter to 0 
 and full-screen-api.transition-duration.leave to 0

none of these help.

Hi   !

Changing the settings for this in   'about:config'   stopped working   (I think)   after   FF 41.
But would you take a look at this:

thanks, setting full-screen-api.warning.timeout to 0 solved the problem
