The error message I get is this:
"Server not found
Firefox can't find the server at uk.youtube.com.
If you are unable to load any pages, check your computer's network
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.
