Firefox won't start Windows 7 (worked fine the first day I installed)

I have followed all the tips in this article http://support.mozilla.org/en-US/kb/firefox-wont-start-find-solutions

I have uninstalled according to the instructions and reinstalled 3 times and each time it works for one day and then the next day or whenver I try and use it again I get the hourglass for a few seconds and then nothing and the profile manager won't run either

Hello klcash01

try to boot the computer in Windows Safe mode with network support (press F8 on the boot screen) and check it again (If works in Windows Safe mode then you have a problem with other software, like security software[antivirus, firewall] or a system driver, that is running on your computer).


thank you

problem solved thanks! when I booted up in safe mode and then tried to open firefox it gave me a message that it was updating and then it worked. When I rebooted into normal mode it's working fine too. Thank you so much. Not sure why it would do it's updates in normal mode? I had my virus protection turned off....
