Hi there I work in an organization that has its Windows desktops totally isolated from the Internet. When I install Firefox to say a Windows Server 2008 R2 and starts Firefox it wont browse internal sites or even open up things like About:config and so on. Its there a start switch, a config file that we need to setup/put in place for Firefox to work isolated from the Internet? We use it to test how different browsers work on sites that our organization uses. In advance Thank JanØ Denmark
