Computer Security & Viruses - firefox

Expert: James Filmer - 6/13/2009

Question
suddenly here is what i get when i try to open firefox, which i have been using for a year with no trouble:

PROXY SERVER REFUSED CONNECTION

firefox is configured to use a proxy server that is refusing connections.

the browser is configured to use a proxy server, but the proxy refused a connection.

    - is the browser's proxy configuration correct? check the settings and try again.

    - does the proxy service allow connections from this network?

    - still having trouble? consult your network administrator or internet provider.

Answer
Dear ian,

One of the following threads should provide the fix for the problem.

(Note: Even if you're using another Firewall, it could still be blocking the connection, especially if you've updated Firefox lately.

If not, please provide more info: Your Firefox version, what proxy addon or server you're using (if any), your Firewall, and did the problem start after a Fx upgrade.

I might check also the Standard Diagnostic steps, especially since it was working without problems for so long and then just stopped working right: http://kb.mozillazine.org/Standard_diagnostic_-_Firefox
