When I clicked on menu of Firefox its appear very slowly, when I place pointer on a arrow also the submenu apear slowly, page scroling not smoothly, typing letter appear word by word. How can I fix it?
I upgrade its version, uninstall & re-installed it. Separately downloaded new version and install it after uninstall old firefox, but no solution I get.

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions or if hardware acceleration 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.

In Firefox 4 and later Safe mode disables extensions and disables hardware acceleration.
