After Firefox updated, all I get when it opens is a "Server not found" message. Windows Explorer and Google Chrome work fine. I verified that i do not us a proxy server. I deleted and re-added Firefox to my list of acceptable programs in Windows Firewall. I updated my Microsoft Security Essentials. What should I do next?

  • Make sure your Internet security software is up-to-date (i.e. you are running the latest version).
