I've opened a video in Full-Screen on my 2nd Display. I know it's in Full-Screen. I am watching this in Full-Screen on my 2nd Display. I do stuff on my 1st Display and i am watching a video on my 2nd Display in Full-Screen at the same time. When i switch back to 2nd Display (click with my mouse on the video which is running in Full Screen), a warning message will pop up that i am watching a video in Full-Screen. YOU DON'T SAY!

I made changes in my config full-screen-api.warning.timeout = 0 full-screen-api.warning.delay = 0 full-screen-api.transition.timeout = 0 full-screen-api.transition-duration.leave = 0 full-screen-api.transition-duration.enter = 0

It's working until i leave my mouse pointer on my 1st display and click on the Full-Screen video on my 2nd display with the Full-Screen video which is running in Full-Screen on my 2nd display in Full-Screen because wanted in Full-Screen on my 2nd display.

If you answer is cause of security reasons, i saw this JOKE Phishing attack example on https://feross.org/html5-fullscreen-api-attack/ So explain me why "full-screen-api.mouse-event-allow-left-button-only" is set to True?

I know many People are mentally challenged but do not punish us. So tell me how can i remove this Full screen Message warning entirely.

Thank you.

You can read this bug report about the reasoning behind the "full-screen-api.mouse-event-allow-left-button-only" pref. Firefox seems to think that you are entering Full Screen mode if you click on that window.

I've got a similar issue as the OP, dual monitor set-up, watching YT on full screen on one monitor, click on 2nd monitor, and warning is displayed "YouTube is now full screen", except the bloody thing stay there, as in forever.

Have made the same config changes as the OP, uninstalled FF, problem still exists.

Could be the final bug to push me over to using Chrome full time!!

What's the deal here?

This should be fixed by Bug 1847901 which will be uplifted to Beta 117. Until that reaches release, you can work around it by changing full-screen-api.warning.timeout to 1.
