I am using 2 monitor, identified as display-1 and display-2.

I split 1 window of the Firefox in the display-1 and another in display-2.

I set display-1 to full screen (using the HTML5 video API), then I focus in the display-2. Just after focusing on display-2, display-1 exits fullscreen with the Title Bar showing on top.

https://support.mozilla.org/en-US/questions/995644 don't helped me.

So if you zoom in and out on the second screen the first one goes out of full screen mode.

I also noticed on the bug that was references that the feature full-screen-api.exit-on-deactivate is no longer visible in about:config. It is possible to add it back. Right click on the about:config page and add a new entry.

Does adding it back make a difference?
