So far I have encountered this on http://www.vgcats.com/ and http://uk.youtube.com/
The error message I get is this:
"Server not found
Firefox can't find the server at uk.youtube.com.
Check the address for typing errors such as
ww.example.com instead of
www.example.com
If you are unable to load any pages, check your computer's network
connection.
If your computer or network is protected by a firewall or proxy, make sure
that Firefox is permitted to access the Web."
I'm sure any FF user has gotten this error before.
All other sites I have tried seem to work fine. But other browsers (Opera, IE7) get the same errors. I use AOL (not out of choice) and I am always connected to the internet via a Netgear wireless router (wired to the PC). When I use the AOL browser, all sites, including Youtube and VGCats, display fine.
Help? :P
