Back around February (2025), the full screen mode by pressing F11 quit working. Clicking the diagonal two pointed arrow in the application menu didn't do it anymore either. Both actions only toggle the bookmark bar. I've tried reinstalling, and waiting for further updates. So far, still no luck. I've since moved on to using another browser, since I often want this feature. Does anyone have the same problem or know how to fix this?

Does that also happen in Troubleshoot mode (https://support.mozilla.org/en-US/kb/diagnose-firefox-issues-using-troubleshoot-mode)?
