When I move my cursor around in firefox, whatever it moves over is then blocked out with dark shapes and lines. How do I fix this?
When I open firefox, the whole screen with google homepage would flick up then it would suddenly be blocked by the whole screen filling in with a dark background and lots of white lines patterning over the screen. I removed firefox and then reinstalled and now the same patterns appear when I move my cursor over the tool bar and anywhere there is writing. I have checked and I don't have any virus's. How do I fix this? Raemer

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).
- Do not click the Reset button on the Safe mode start window or otherwise make changes.

Try to disable hardware acceleration in Firefox.
- Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"
