(Whiteboard: [mac:multimonitor])

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.14; rv:63.0) Gecko/20100101 Firefox/63.0 Steps to reproduce: Setup: iMac (Retina 5K, 27-inch, 2017) with MacOS Mojave + DELL 4k monitor. 1 window maximized on second screen, 1 normal window on iMac screen. 1) Try to click yellow dot (upper left corner) to minimize window. 2) Tried CMD+M Actual results: 1) Yellow dot is greyed out. 2) CMD+M doesn't work at all Extra issue is the top bar (with the Apple icon, clock etc) is hidden even on the iMac screen, where there aren't any maximized windows. Expected results: Yellow dot shouldn't have been greyed out. When clicking on it or pressing CMD+M the window on the iMac screen should have been minimized to the task bar at the bottom of the screen.

This problem is still occurring on macOS 91.0.2 if another Firefox window is full-screen on any monitor of a multi-monitor setup.

The menu bar and dock will also not appear if Firefox is in the foreground on a second monitor unless you click on another non-Firefox app window or the desktop, and it is not possible to minimize other Firefox windows while any Firefox window is full-screen.

Setting this to NEW as I can reproduce it on macOS Big Sur 11.6 using Firefox 91.3.0 esr, Firefox 94.0.1, Firefox 95 beta, and the latest Nightly 96.0a1. On multimonitor setup, the minimize button on screen 1 is grayed out if on screen 2 a video is playing in full screen.

With Firefox 150 and macOS 26.5 I'm not able to reproduce the primary problem reported here or the secondary issues with the dock and menu bar. Tested with a retina display and a 4k second monitor. Minimizing works as expected, no dock issues.

A lot has changed since this was reported. Closing as WFM since I don't know exactly when or how this was resolved. Please reopen if you're still able to reproduce.
