Firefox browser on mac with multiple screens

My Firefox browser shows like the image I have attached. I am using multiple screens (3) them main screen from the mac computer, and two extra screens. On the main screen Firefox displays fine, but on the other screens I get the image shown in the attachment with no menu...nothing. Note all my other browsers work fine on multiple screens.

Note I am using MacOS Sierra version 10.12.4 I have tried reinstalling Firefox as well.

Do you have any idea what might fix the problem?

You can try to disable hardware acceleration in Firefox.

  • Firefox -> Preferences -> Advanced -> General -> Browsing: "Use hardware acceleration when available"

You need to close and restart Firefox after toggling this setting.
