HIigh Res Screen
I use two monitors one of which is a high resolution (3840 x 2160). Firefox displays perfectly on my second screen (1920 x 1080) but if I move Firefox to the high res screen I lose the top row i.e. the Tab indicator and vitaly the Minimise, Maximise and Close symbols. It is then impossible to move Firefox back again.
When I change the high res to (say) 2560 x 1600 the problem disappears in that I can now se the entire Firefox output but the vertical edges of the total display are shrunk and black edges appear.
Is there an easy solution? I'm loathe to use any lower resolutions.
Thanks

Firefox may have a problem if there are multiple monitors attached with different resolution.
You can try to disable hardware acceleration in Firefox.
- Options/Preferences -> General: Performance
remove checkmark: [ ] "Use recommended performance settings"
remove checkmark: [ ] "Use hardware acceleration when available" - https://support.mozilla.org/en-US/kb/performance-settings
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.
