Whenever you visit YouTube or any video sharing site, and try to play a video in full screen, a message appears on top saying ‘YouTube is now fullscreen. Press Esc at any time to exit.’ When you click ‘Allow’ or ‘deny’ button, and check ‘Remember decision for YouTube.com’, the same popup appears again for another video when played in fullscreen, that’s annoying, let us see how to disable this Youtube.com is now in the full screen popup in Firefox.
Google makes HTML5 Player default for Playing Videos on YouTube in Chrome and Firefox
UPDATE 1: Firefox 43: Mozilla makes Full Screen Messages for YouTube Videos Less Annoying
UPDATE 2: Firefox 43+: Remove ‘youtube.com is now full screen’ notification
Disable ‘youtube.com is now fullscreen’ popup in Firefox browser
1. Visit about:config
2. Find full-screen-api.approval-required preference and change its value to ‘false’.
Enable Media Source Extensions in Firefox for a better YouTube Player
Is this working for you? Is there any way to disable the same in Chrome?
Thank You! EVERYTIME I saw the message I reminded myself to look through about:config to see if I could find anything relevant but of course never remembered to do so after the video! SMH. Appreciate it!

Why so many programs are unnecessarily complicated, and especially user-UNfriendly I’ll never know. If it wasn’t for folks like you making the internet easier to use, I’d probably just give up.
Oh MAN Thank You sooooo much !! :-)

The dumbing down of the internet is doing my bloody head in
Thank you, my god that shit gets old fast
This does not work as of Firefox 42.
Decimus, Mozilla has changed the fullscreen notification appear in Firefox from version 43 onwards, you can have the ability to disable in Firefox 43 but not in 42, sorry no option left at present if you find it annoying.

It still doesn’t disable with version 43 (at least with the old api = false setting).

no preference name full-screen-api.approval-required in firefox 44. how can i change it
This https://techdows.com/2015/10/firefox-43-remove-youtube-com-is-now-full-screen-notification.html
With the newest version of firefox try changing full-screen-api.warning.delay and full-screen-api.warning.timeout to 0
full-screen-api.warning.delay
full-screen-api.warning.timeout
I changed both to 0 (zero) and now it works. (v. 43.0.1)

https://techdows.com/2015/10/firefox-43-remove-youtube-com-is-now-full-screen-notification.html I haven’t found Enter full screen setting in permissions dialog, may that has existed in older version of Firefox, but not now.
