Hello,

Try changing widget.windows.fullscreen_marking_method Firefox preference to 1, 2 or 3 in the Configuration Editor:

  • Type about:config in the address bar and press Enter.
  • A warning page may appear. Click "Accept the Risk and Continue" to go to the about:config page.
  • Enter widget.windows.fullscreen_marking_method in the Search preference name box.
  • Set the widget.windows.fullscreen_marking_method preference (named exactly like that) to 1, 2 and then 3 by clicking the Edit Fx71aboutconfig-EditButton button (or just double-clicking on the preference), every time checking if the problem persists.

For reference, see this discussion and the corresponding bug.

Looking forward to your update on how it goes!
