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 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.
I've tried all aspects of troubleshooting listed in the links you provided, tried starting in safe mode, disabling add-ons, extensions, and using default theme. nothing seems to be preventing the problem any other suggestions would be helpful and greatly appreciated.
