Pages do not display right on large pivoted screen
When displaying long pages on the large pivoted screen (2500x1440), black banners appear across the page hiding underlying contents. The heights and positions of these are random. When changing the zoom the heights and positions of these "black-out" banners change. Other browsers display the same pages 100% fine. The other screen attached to the same PC works OK. The same screen pivoted back to landscape works 100% OK. When switched back to portrait - wrong again.

(Note: This should be Pinned and run Weekly, If never done below expect 10's of gig's) Then run it again and click the button that says Cleanup System Files. Note: your Firefox Profile is saved.

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 to make the change effective.
You can check if there is an update for your graphics display driver and check for hardware acceleration related issues.
