Trouble opening web pages in both Safari and Firefox

[jahbuzzz]

This is the error that comes up on seemingly random pages:
Server not found


Firefox can't find the server at www.bidnapper.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.

The laptop seems to work fine...

Anyone? 😕

Is it the same site all the time, or does it vary between sites? If its the same, it could be a firewall or filter somewhere (Is it in 1 location where you dont own the network? or is it constant) - Id check your Firewall settings - seems most likely to me that its stopping certain sites, or your network owner/ISP is.
