I've re-installed Firefox and changed Firefox's proxy settings amongst other suggestions that were made on a similar page. It was Firefox 3.6, but I tried installing the 4 version. And no one has been around to live chat with, pretty lame that its offered if I can't even use it.

Did you check your security software (firewall)?

A possible cause is security software (firewall) that blocks or restricts Firefox without informing you about that, possibly 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 Server Not Found - Troubleshoot connection problems and Configure firewalls so that Firefox can access the Internet and http://kb.mozillazine.org/Firewalls


If you use a Firefox 4 beta release then you should create a new profile exclusively for the 4.0 beta version and create a desktop shortcut with -P "profile" appended to the target to launch that profile.
