I have seen issues before where there is a clash between IPv4 and IPv6, in Firefox you can change settings by browsing to about:config
If you set the value of network.dns.disableIPv6 to true, you may find that this resolves the issue (assuming the nslookup worked)
I changed that, restarted ff, and Bang!!! all is peaches and gravy!
