scrolling makes screen go blank until I click near top. Individual boxes go black. The 3.7 version works fine.
Every time I move mouse over a box, it goes black. moving elsewhere restores it. If I scroll with cursor or mouse whole screen goes black except for some of the navigation at top. If I click at top, screen comes back.

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
- Don't make any changes on the Safe mode start window.
- https://support.mozilla.com/kb/Safe+Mode
In Firefox 4 you can use one of these to start in Safe mode:
- Help > Restart with Add-ons Disabled
- Hold down the Shift key while double clicking the Firefox desktop shortcut (Windows)
In Firefox 4 Safe mode disables extensions and disables hardware acceleration.
- Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"
If disabling hardware acceleration works then check if there is an update available for your graphics display driver.
It blacks out when I try to click on Firefox.
Did you try to start Safe mode via holding down the Shift key and a double click on the Firefox desktop icon?
Yes. I did that, but it still blacks out.
I can't find a help menu. It gives few options.
This isn't worth the trouble. This is the fifth time I've tried 4. I'll go back to 3. It works fine. I don't have to put up with this aggravation. Software should work for me not the other way around.
