That's weird.

From the test scripts all skipping, it seems that telnet can connect. So I suggest you consult with your system administrator as to why that would be while Firefox cannot connect from the same machine.

I was reading the documentation for MozRepl and found this:

In cygwin, please add binmode param as 1 in client args.

    $repl->setup({
        client => {
            extra_client_args => {
                binmode => 1
            }
        }
    });

Is the above relevant to www::mechanize::firefox? How would I implement the above using the functions included in www::mechanize::firefox?

WWW::Mechanize::Firefox uses MozRepl::RemoteObject, which uses MozRepl, so this could be relevant. I don't use Cygwin, so I don't know if this really is relevant.

I think the easiest way is to pass in a preconstructed MozRepl object when constructing the WWW::Mechanize::Firefox object.
