IT JUST STOPPED! Even the Geek Squad can't get it to work. Seems like it was working fine then it didn't. Get this message for EVERY site: "Firefox can't establish a connection to the server"

Thank you for your reply. I followed the instructions, but the changes did not fix the problem. Not certain where to go from here. I LOVE Firefox and do not want to abandon it. Any suggestions?

You may have already gone through these from the links, but if you haven't, I hope this is helpful: Firewalls and McAfee settings.

Let's hope it holds :) Thanks for posting the details. Please note that if the McAfeee rules and confs weren't deleted when uninstalling, the problem may resurface.
