Check the proxy settings under Tools -> Options -> Advanced - Network tab, Settings button.
You probably want No Proxy, if it is set to anything else.

http://fastun.com (a registration required web accelerator / anonymizer) indicates it has some sort of Firefox add-on. Do you see a relevant one in Tools -> Add-ons -> Extensions? Try disabling it.
If you are not sure which one it is, try Diagnose Firefox issues using Troubleshoot Mode to disable all of them.
