Something wrong with Firefox

Every time I get on, no matter what the page, it always says "Firefox can't establish a connection to the server at (Page name here)" and it's starting to grind on my nerves...I'm typing here from IE, and I can't stand IE.

make sure your proxy settings are not on by going into tools general tab and clicking on connection settings then clicking on direct connection to internet. Try that solution first then well see if it helps.
