lost red X, back arrow and all icons on menu bar
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.

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.
Unable to find Microsoft Paint but I placed print screen on Word. Not sure how to send this to you.
Just found paint and attached it.
