Hi Peter_M, can you help to check if this is a recent regression around 74? If yes, possible to get a regression window? Thank you.

Hi,

I believe this is not a regression, the issue is reproducible all the way back to Nightly 53.0a1.

This actually isn't dependant on the number of the screens, can be reproduced by having multiple windows open in fullscreen.

Steps:

1. Open two separate firefox window
2. toggle full screen on both windows (i.e a video), you can use alt-tab to switch between multiple fullscreen windows
3. make sure one of the two windows has focus
4. press esc button

Just adding a comment that in Firefox 124.0, this bug is still present despite onboarding to the MacOS fullscreen API, in that if you have two windows fullscreened with an app like YouTube, escaping one escapes both/all. The only difference now is that when re-entering fullscreen, it properly re-enters, whereas previously, it would enter a windowed-mode-adjacent version.

I was able to reproduce the issue with an affected Firefox Nightly build 140.0a1 using macOS 14, as described in Comment 0 and Comment 9.
Verified as fixed using Firefox 142.0b9 on macOS 14, Windows 11 and Ubuntu 22.04. Pressing Esc exits full-screen mode only for the active window.
