Mac OS Monterey Full Screen Bug
Hello,
I am in the process of transitioning over to Firefox, however, for some reason it will not open in full screen. I am working with MacOS Monterey. When I go to click on green full screen button the window freezes, all the settings boxes up top disappear and the browser just totally freezes. I can't even access the 'view' menu to get out of full screen, I have to just quit the application and only use the browser in the minimized version. Please see attached screen shots of the issue I am facing. The first image shows what happens the the drop down menu after attempting to go into full screen, and the second image shows what the browser gets frozen on when I attempt to enter fullscreen. Furthermore, attempting to take any action once the full screen button has been pressed does not work except exciting the application. The window simply just stays frozen or when I click a drop down menu like view the program disappears, and the OS acts like no windows are open for Firefox. Any help would be greatly appreciated.
Thank you.

Hello Paul,
thank you for that. I have just checked this and there are no logged crashes at all. The program does stay open, the window just disappears and does not enter full screen mode. I have found many threads about the issue with the toolbar issue some people were having but this is completely different. It is hard to explain so if allowed I do have a screen recording of the issue on an iCloud share link.
The best I can explain in words is that when attempting to enter full screen mode from desktop on Firefox the program freezes and never does anything, the only time I have gotten anything to happen was when I click on one of the OS drop down menus the menu goes clear as shown in screenshot 1 or my original post and the window completely disappears.
Please let me know if I can attach the screen recording link to my next reply.
Thank you for your assistance

This thread seems to have the same issue I am currently dealing with. Please see attached link. [[Mac OS Montery (and before):Firefox is freezing and then crashing whenever going full screen.]] https://support.mozilla.org/en-US/que.../1377103 The troubleshooting from this thread did not work in my case.
Here are some steps you can try to resolve the full-screen freezing issue:
Update Firefox: Ensure that you're using the latest version of Firefox. Outdated versions may have bugs that have been fixed in newer releases.
Update MacOS: Make sure your MacOS is up-to-date. Sometimes, system updates can resolve compatibility issues with third-party applications.
Extensions/Add-ons: Disable any browser extensions or add-ons one by one and try entering full-screen mode after disabling each one. Sometimes, extensions can conflict with full-screen functionality.
Safe Mode: Launch Firefox in Safe Mode to rule out any third-party interference. To do this, go to the Firefox menu > Help > Restart with Add-ons Disabled.
Clear Cache and Cookies: Excessive cache and cookies can sometimes cause issues. Go to Firefox preferences, find Privacy & Security, and then Clear Data. This will remove cached web content and cookies.
Hardware Acceleration: Experiment with hardware acceleration settings. Go to Firefox preferences, search for "Performance," and disable or enable hardware acceleration to see if it makes a difference.
Create a New Profile: Sometimes, issues are profile-specific. You can create a new Firefox profile to see if the problem persists there. To do this, open Terminal and run: open -na "Firefox.app" --args -ProfileManager, then create a new profile.
Reset Firefox: As a last resort, you can reset Firefox to its default settings. This will retain your bookmarks but remove customizations and extensions. In Firefox, go to Help > Troubleshooting Information, and click "Refresh Firefox."
Check System Preferences: Verify your MacOS system preferences for display settings, resolution, and scaling. Make sure everything is set correctly.
I have tried all the above troubleshooting suggestions, and still it seems to not work. I also checked to see if full-screen-api.macos-native-full-screen is marked as true and it is. I also do not have any add ons or extensions on Firefox as of yet.
