I can't see the drop down menus when firefox is on my second monitor

more options

I use 2 monitors, extended desktop. On my extended desktop the Firefox drop down menus appear to be invisible or flash on and off. On my primary desktop Firefox works fine. When I change the extended monitor to primary Firefox works fine.

So it seems to be a problem when Firefox is viewed on the extended desktop regardless of which monitor is being used.
