Hi all, After use the Firefox on a secondary large screen, when opening on the laptop screen, it doesn't fit automatically and we see a large blank screen. After we need to move down and resize it to fit. Is it possible to resize automatically or at least align to the top of the screen, when Firefox window size is larger than the screen size? That's only a suggestion, i don't know if I'm doing it on the correct forum. Thanks and keep safe.

You can try to disable hardware acceleration in Firefox.

Close and restart Firefox after modifying the setting for changes to take effect.

You can check if there is an update for your graphics display driver and check for hardware acceleration related issues.
