<p>Firefox only keeps track of modified preferences in the <em>prefs.js</em> file in your profile folder. If you rename this file while Firefox is closed, you'd start over with the default set of preferences (though any add-ons you have installed would create preferences again once Firefox is restarted). It's also possible to set preferences at startup in <em>user.js</em>, or to lock them for all users.
