I am using Windows XP SP3 and I had Firefox 3.5.7 installed and everything worked great. I installed the update to 3.6 and it worked great until I restarted my computer this morning and Firefox crashed and sent in a report. I can not shut down my computer now without pushing the front power button. I went to control panel and tried to open add/ remove programs and that would not work. I also went to restore to an earlier date and that froze up and would not work. I can get IE 7 to open and my Thunderbird email is working. I am using a Dell 4550 and have never had a problem before. It is a Pentium 4 CPU 2.53 GHz, 1.00 GB RAM.

Any help will will be appreciated.
