Why is my screen dark since my update earlier today?
Launched program after an update on 10/14/14 and the screen is black except for where the banner should be across the top. I tried to uninstall and reload but got the same result.

Could you try starting Firefox in its Safe Mode? That's a standard diagnostic tool to deactivate extensions and some advanced features of Firefox. More info: Diagnose Firefox issues using Troubleshoot Mode.
With Firefox fully closed, you can hold down the Shift key when starting Firefox.
A small dialog should appear. Click "Start in Safe Mode" (not Reset).
Any difference?
If Firefox is visible, go ahead and disable Firefox's use of hardware acceleration as a workaround for a possible graphics card driver software incompatibility.
"3-bar" menu button (or Tools menu) > Options > Advanced
On the "General" mini-tab, uncheck the box for "Use hardware acceleration when available"
That will be in effect the next time you exit and start Firefox back up.
