Firefox (Opera and Chrome) won't load pages, but IE does.
Firefox only displays the home page with the Firefox symbol and search bar. I try to go to a site and it says "Server Not Found", Opera and Chrome won't even open, but Internet Explorer works fine. I tried "No Proxy", IPv6, and DNS Prefetching...none of that changed anything. I have a XP with Service Pack 2.
EDIT: I changed the Firewall settings on Norton 360 to "Allow", but still no change.
EDIT (12/01): All servers work on Administrative account on computer, but not mine (Guest, etc.).

Sometimes a problem with Firefox may be a result of malware installed on your computer, that you may not be aware of.
You can try some of the following programs to scan for malware:
- MalwareBytes' Anti-Malware
- TDSSKiller - AntiRootkit Utility
- Microsoft Security Essentials (A good permanent anti-virus if you don't already have one)
Further information can be found in the Troubleshoot Firefox issues caused by malware article.

Some firewalls like Norton can be very persistent in allowing a specific Firefox version and current rules may still apply to a previous Firefox version and not to the currently installed Firefox version.
A possible cause is security software (firewall,anti-virus) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.
