Does the issue still occur if you start Firefox in Safe Mode? http://support.mozilla.com/en-US/kb/Safe+Mode

How about with a new, empty profile? http://support.mozilla.com/en-US/kb/Basic%20Troubleshooting#w_8-make-a-new-profile

Please provide an example of a site hosted at GoDaddy. Can you go to godaddy.com?

Did you check your security software (firewall)?

A possible cause is security software (firewall) 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 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.

Thanks, but I tried turning the fire wall off. (I'm using Window's firewall.) I doesn't make any difference. I even tried to shut off the firewall, restart the computer and get to my website, it didn't work.

Hi, Thanks, Ok, so I tried safe mode, no go. I also created a new profile, also no go. I can get to godaddy.com I cannot get to www.guybert.com or www.dunsmoredairygoats.com or saginawstoveworks.com or any of the other sites that I have hosted at godaddy.

I can get to those sites with IE 9 and Google Chrome 14 on the same computers and from the same locations that firefox fails from.

Do a malware check with some malware scanning programs.
You need to scan with all programs because each program detects different malware.
Make sure that you update each program to get the latest version of their databases before doing a scan.

I've tried several anti-malware problems, nothing. As I said before, this is happening on more than one computer. And, it is happening on Win7 pro, win7 home, and Ubuntu

You can try to reset (power off/on) the router if you use one.
