How to configure firefox 3.6 proxy through ssh terminal on ubuntu 8.04

Question

I am trying to configure Firefox proxy through an ssh terminal (putty) on Ubuntu 8.04. There in no GUI for the terminal, so am using xvfb to simulate the display. However Firefox cannot open any website because the proxy is not set correctly
Here's what I tried.Edited a loadcustom.js file in
/usr/lib/firefox-3.6x/defaults/prefs
and added the lines
// tell firefox to load customized config file
pref("general.config.obscure_value", 0);
pref("general.config.filename", "firefox.cfg");
Then created a firefox.cfg file in
/usr/lib/firefox3.6x and added the lines
// Lock specific preferences in Firefox so that users cannot edit them
lockPref("app.update.enabled", false);
lockPref("network.proxy.http", "my-proxy.in-my-domain.com");
lockPref("network.proxy.http_port", 8080);
lockPref("network.proxy.type", 1);
lockPref("network.proxy.no_proxies_on", "localhost, 127.0.0.1, 192.168.1.0/24");
lockPref("network.proxy.share_proxy_settings", true);
lockPref("browser.startup.homepage", "http://www.google.com/");
This did not work for me. Any suggestions?

Never mind. I got it working now, I was editing at the wrong place I guess.
I had to add the settings in /usr/lib/firefox-3.6.17/defaults/pref/firefox.js and then restart Firefox. Here's what I added
pref("network.proxy.type", 4); to have Firefox auto-detect proxy settings.
