Everything is whited out on menu bar (no icons are visible), there is no Red X, or back arrow visible. The X is very faint and blue when I place the cursor over the spot where it is located. I can get out by placing the cursor where the arrow or back button should be and clicking, but nothing is visible. Everything shows when I use Explorer. I am using Windows 8.1.

You can try to disable hardware acceleration in Firefox.

  • Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"

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

Can you attach a screenshot?

  • Use a compressed image type like PNG or JPG to save the screenshot
  • Make sure that you do not exceed the maximum size of 1 MB

You can try to disable OMTC and leave hardware acceleration in Firefox enabled.

  • about:config page: layers.offmainthreadcomposition.enabled = false

You can open the about:config page via the location/address bar. You can accept the warning and click "I'll be careful" to continue.

You can use one of these to start Firefox in Safe Mode:

  • On Mac, hold down the Options key while starting Firefox
  • Help > Restart with Add-ons Disabled
