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.

Thanks for the try but all I have is Default in the Appearance/Themes. Hope it either sorts out with another update or someone has another option to try :S

Try to update Firefox to the latest version via "Help > About Firefox" or "Help > Check for Updates"

You can find the latest Firefox release here:

• Firefox 9.0.x: http://www.mozilla.org/en-US/firefox/all.html

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

See "Basic Troubleshooting: Make a new profile":

• https://support.mozilla.org/kb/Basic+Troubleshooting#w_8-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.

Thanks for all the help but nothing is changing it, I'm starting to think that the format may have changed when it updated... if it did it's annoying as anything and I don't like it one bit
