how can i remove fullscreen popup message forever?

[99]

this full screen warning message popup is **bleep**ing annoying. i tried to disable this piece of trash in about:config and so on and this trash reapears. everything was set to 0 and is still there.

so tell me how to remove this **bleep**. i ask you how to remove and not how to DiSaBlE.

I'm not sure what distinction you are making between "remove" and "disable." This is what I have, which gives the barest blip that I hardly notice. YMMV.

(A) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button accepting the risk.

More info on about:config: Configuration Editor for Firefox. Please keep in mind that changes made through this back door aren't fully supported and aren't guaranteed to continue working in the future.

(B) In the search box in the page, type or paste full-screen-api.warning and pause while the list is filtered

Firefox should display two preferences.

(C) Double-click the full-screen-api.warning.delay preference to display an editing field, and change the value to 50 then press Enter or click the blue check mark button to save the change.

(D) Double-click the full-screen-api.warning.timeout preference to display an editing field, and change the value to 50 then press Enter or click the blue check mark button to save the change.

If that doesn't suit your needs, perhaps you'll find another recommendation in a web search for either of those preferences.

Thanks Jscher2000, That corrected this issue for me. I was also trying to disable this notification due to it causing issues with other applications on my PC.

I set it to the max value which essentially disabled it. Thanks!

About:config does not work in Firefox Mobile release versions so the advice is useless on a phone. Since the last update a few days ago, Firefox decided to pop up "To exit full-screen, slide down and click back" messages complete with an icon over top of YouTube every single time you click full-screen (as if saying it once isn't enough). There is no way to remove this incredibly annoying pop-up that I can find.

It's just unbelievable how egotistical the FF devs are that they won't give any options to configure the browser the way you want it to be. The only reason I still use it is you can get an adblock and ublock origin extensions for it (Chrome is advertising central!). Sorry, but insane amounts of non-stop ads have ruined the internet. The internet is almost unusable without them.
