When netscape connects to a http server,
it's sends something like this:

        GET / HTTP/1.0
        Connection: Keep-Alive
        User-Agent: Mozilla/4.73 [en] (X11; I; FreeBSD 4.3-RC i386)

And when you send a mail, in the headers you can see:

        X-Mailer: Mozilla 4.73 [en] (X11; I; FreeBSD 4.3-RC i386)

So, 2 questions:

1) How netscape gets info from the O.S. and version (uname perhaps?)
2) How can I hide that info.

I remember that wwwoffled has an option to hide the user agent, but
i want to know how to prevent netscape to get it.
