See detail in original question. Here is the text from the dialog box which comes up, with fields for Username and Password: "The proxy fastun.com:7000 is requesting a user name and password. The site says: "fasTun"." This means I'm unable to use MFF. I've uninstalled MFF and re-installed MFF and the same occurs. The problem arose after I'd been surfing the Net and got to a German site. From that point onwards my internet became very slow. When I ran "speedtest.net" my computer was going thruugh Frankfurt, Germany, instead of Canberra, Australia! Can you please help?

This happened

Every time Firefox opened

Following my doing a System Restore to a point prior to the computer slowing down. From that point on I've been unable to use MFF to connect to any websites. The problem does not appear using Windows Internet Explorer 8, nor is there an issue with speed of downloads.

Chosen solution

Check the proxy settings under Tools -> Options -> Advanced - Network tab, Settings button.

You probably want No Proxy, if it is set to anything else.

See https://support.mozilla.com/en-US/kb/Options+window+-+Advanced+panel#Connection_Settings_Dialog

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.
