Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the add-ons is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Appearance/Themes).
- Don't make any changes on the Safe mode start window.
In Firefox 4 Safe mode disables extensions and disables hardware acceleration. Check if there is an update available for your graphics display card driver.
Disable hardware acceleration:
- Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"
