Programatically change proxy settings from an external application


Using pref.js or a pac file suggests that firefox will only load settings when it opens. I would like to manipulate settings from an external program, and have firefox reload them instantly when I change them.

I have an external application and with it i want to change proxy settings and have firfox use them instantly.

Can this be accomplished? From the registry maybe...?
