Hello, There are a number of Firefox settings that I need to lock down before I can deploy Firefox in my company. In particular I need to disable the ability to install Add-Ons. Please correct me if my understanding is incorrect but it does not appear that Firefox preferences are stored in the Registry and therefore Group Policy will not be much use. - Can someone point me to a method of using the prefs.js or mozilla.cfg to control Firefox - I cannot seem to find documentation on these? - How can I pre-package these files so that the installer copies them to the correct locations? Thank you, Matt
