Other Is there a way of turning of "is now full screen" message on flash?

Every time I go fullscreen in a video like on Facebook, YouTube etc. a message appears at the top saying '(website) is now full screen' with a derp button to 'exit full screen (esc)'.

Can I get rid of this incredibly annoying and pointless notification that blocks the view of a video for a good few seconds?

 

It's browser security thing to stop less scrupulous sites taking over your screen rather than a flash setting, though there is a way round it in Chrome by, essentially, white-listing everything...

Go to -

Code:

chrome://settings/contentExceptions#fullscreen

and 'Allow'

Code:

*://*/*

and it should stop asking you... though you still get a brief 'Press [Esc] to exit full screen' popup, bit it's far less intrusive.

 

The brief popup is what I'm trying to get rid of, and I'm using Firefox.

 

had a quick rummage through about:config in FF and by the looks of it i don't think you can...

 

With the proviso that I haven't actually tested it, as with most things in Firefox, there seems to be an addon for that: https://addons.mozilla.org/en-gb/firefox/addon/disable-html5-fullscreen-alert/

 

Now if they could just fix Facebook being a big memory leak...
