1831016 - Unable to exit "full screen" mode.

Status: RESOLVED DUPLICATE of bug 1829403

(Firefox :: Untriaged, defect)

Description

[haillecoyote]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:109.0) Gecko/20100101 Firefox/112.0

Steps to reproduce:

MacBook Pro (Retina, 15-inch, Late 2013) MacOS Big Sur 11.7.6 (20G1231) Opened Firefox app, clicked on green expansion button to put into full screen mode, opened a new tab, clicked on Youtube icon and opened Youtube, started playing a vid, then put into full screen mode by clicking the full screen icon. Tried to exit full screen mode by pressing escape or clicking on the "exit full screen" icon, but no response to either. The same process but with Netflix has the same results.

Actual results:

Once in full screen mode, all other tabs and browser search bar are unavailable. The only way to use Firefox for any other purpose (and to exit the full screen mode) is to quit Firefox, and then reopen it. Not having this problem with Safari or Chrome, and it has been happening for a couple of weeks.

Expected results:

Normally when Firefox is put into full screen mode, and a video is placed into full screen mode, and then the escape key is pressed or the exit full screen mode icon is clicked on, then the window returns to a smaller size and the browser tabs and browser search bar become available. And if the escape key is pressed again while the video is not in full screen mode, the Firefox browser leaves full screen mode on the mac desktop.
