AVG Internet Security is a software package for Microsoft Windows. It includes a firewall component, which controls which programs can access the outside world. If AVG Internet Security is not set to fully allow Firefox, Firefox will be unable to connect to web sites and may generate “Server not found” errors.

This article describes how to configure AVG Internet Security 8.0 to give Firefox access to the Internet.
