Hello, it‘s been a while I‘m having issues with playing the full screen videos on multiple displays setup.

Summary: When I start the full screen video, the system tray on other displays disappears. I can display it by activating different app on the other display but when I want to play the full screen video on one display and work in other Firefox window on another display, the system tray is not visible.

Version: 108.0.2 (64-bit) and many older versions.

OS: macOS 13.0.1

Reproducible: Always

Steps to Reproduce: Open the Firefox window. Open a new tab and move this new tab on another display. In the first tab, play some video in full screen mode. (E.g. some YouTube video.)

Actual Results: The system tray is not visible on all displays without the full screened video.

Expected behavior: The system tray is visible on all displays without the video playing in full screen mode.

Workaround: Firstly opening the tab with video in full screen mode (⌃⌘F) and then entering the full screen video ensures the visibility of system tray on other displays.

The system tray is visible also when working with other apps but Firefox. (Not possible when need to work in other browser window.)

Do you have this issue as well, how should we proceed?

This behavior is caused by a preference setting in macOS' System Preferences – your Mac has to allow each display to have separate spaces for you to be able to use other displays when an app is full screened.

Thank you for your reply. Of course, I use separate Spaces. This option is enabled in System Settings (System Settings > Desktop & Dock > Displays have separate Spaces). So the issue is not caused by the OS settings. Nevertheless, several others mainstream browsers don’t have such issue on macOS.
