Here's another image with the windows showing in alt-tab mode (whatever that's called - pressed Super button once).

While Firefox is already open, after logging in with the lock screen, or modifying display settings, sometimes Firefox will lose the titlebar, address bar, buttons, and bookmark bar. The website being displayed will still show, however not all features are usable (right click menu, mouse icon doesn't change). Reproduction steps: - Change zoom level of one or more monitors to >1.0 but less than 2.0 (have not tested with non-fractional zooms) - Open Firefox and browse to any website - Lock screen or leave computer alone until the screen locks. - Login - Firefox may have lost the window chrome Workaround: - Open Display Settings - Change display settings or zoom level, then change back.
