Internet Explorer is the only program on my computer that can access the internet

more options

From one day to the next, the only program that can access the internet is Internet Explorer. I do not use it otherwise, I only use Firefox. Thunderbird can no longer access the internet, AVG can't, only Internet Explorer. From a command prompt I can ping my router, Google and other internet sites, so my hardware is fine. Any help would be appreciated

This happened

Every time Firefox opened

How about your Firewall permissions? http://support.mozilla.com/en-US/kb/Firewalls

I should have said that I have done extensive trouble shooting, uninstalling and disabling any and all firewalls to eliminate that as an issue. This happened from one day to the next, with no changes in my system that I am aware of. BTW I am using Windows 7 with Firefox 3.6.8
