Firefox stops loading pages and hoses internet connection for all other apps

Running Firefox 3.6.3; XP sp3; FSecure Client Security 9 After using Firefox for a while - sometimes a few minutes, sometimes a few hours, it will stop loading pages. If I click on a link, nothing happens. The program still responds to key / mouse input, but refuses to load any new pages. Furthermore, it stops all internet connections from my machine, so that IE and Opera stop working. I think it also stops email, but I am not sure.

If I quit Firefox, the process is still running and I have to quit it manually from Task Manager. That solves the problem and internet connections are restored.

I have tried in safe mode, I have tried removing all extensions, I have tried deleting my profile and doing a clean re-install. It's driving me crazy. Any thoughts?

A possible cause is security software (firewall) that blocks or restricts Firefox without informing you about that, maybe after detecting changes (update) to the Firefox program. Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox.

See Configure firewalls so that Firefox can access the Internet and http://kb.mozillazine.org/Firewalls

Hi - thanks for the response, but I have tried that. The firewall does not seem to make any difference. Any other suggestions?
