I can't load any website. It says "Server not found". I have McAfee Host Intrusion Prevention Firewall installed on my computer. How do I fix this?

What is you computer system and Firefox?

Some added toolbar and anti-virus add-ons are known to cause Firefox issues. Disable All of them.

Type about:preferences#advanced<Enter> in the address bar.

Under Advanced, Select Network. Look for Configure How Firefox Connects and press the Settings button. Check the settings.

Some problems occurs when your Internet security program was set to trust the previous version of Firefox, but no longer recognizes your updated version as trusted. Now how to fix the problem: To allow Firefox to connect to the Internet again;

  • Make sure your Internet security software is up-to-date (i.e. you are running the latest version).
  • Remove Firefox from your program's list of trusted or recognized programs. For detailed instructions, see
