After applying a routine update on Windows XP, I started getting "not responding" on shut down and had to cancel the task through Task Manager. The "not responding" error moved to selecting items on a screen and had to cancel through Task Manager. I applied the latest updates and that did not fix the problem. The last update was 34.0.5 and FireFox would not start up. I saw that several people also had this same problem with Windows 7 (although my Windows 7 works ok - knock on wood).

34.0.5 would come up in SafeMode but not otherwise. I did a Reset and FireFox did start with with Extensions disabled. The first extension I enabled was Norton 2014 Toolbar and FireFox did not come up. After applying all of the available NIS fixes, FireFox did come up with the NIS 2014 enabled and seems to function normally at this present time.
