Where does FireFox get the default value of a preference from. What is the format of the file that has the default value?. I need the actual default value for a particualr preference. About:config does show some default values but I need the source from which about:config picks up the default value. Any help in this direction is greatly appreciated.

The prefs that aren't hidden if they are the default are stored in two JavaScript text files in the Firefox program folder You can open them via these links in a Firefox tab: resource:///defaults/pref/firefox.js resource:///greprefs/all.js
