Check your proxy settings

Go to Control Panel and select Internet Options
Select the Connections TAB
Select LAN settings button
Ensure there is no tick in the Proxy Server box
Select OK and restart Internet explorer

And for Firefox there are instructions on this page and you want the setting to be no proxy
