When I select Options from the Tools menu this hangs Firefox and any tabs that may be open. I have to End the non responding program through Task Manager.

This happens any/everytime I try to access Options.

This only happens on my laptop, not my PC. It works fine on my PC. I am on Firefox 6.0.2

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).


Create a new profile as a test to check if your current profile is causing the problems.

See "Basic Troubleshooting: Make a new profile":

There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins" in case there are still problems.

If that new profile works then you can transfer some files from the old profile to that new profile, but be careful not to copy corrupted files.
