I found the answer. Due to a change in the servers at Netfirms, ".dc1" has to be added to the URL after the domain name. Change your URL to http://gorillasafaris.dc1.netfirms.com and it will work. For some reason, only Mozilla seems to require this. IE will work with or without the .dc1.

http://www.gorillasafaris.netfirms.com loads in IE and not in firefox. Firefox claims website cannot be found in browser. Me thinks firefox is now poor browser. What is the problem?
