I am looking for a way to push/lock an add-on to be enabled for all users on a machine. I found one way by using the extensions.enabledAddons in the Mozilla.cfg with the function lockPref, but this Forces me to put as value all the add-ons that should be enabled. This may differ from machine to machine.. What I am hoping or looking for is maybe a property of the add-on object, either in the registry, or in a configuration file from Firefox, something where all add-ons from the machine would be listed, and I could somehow force this particular one to have the property set on enabled, and preferably lock it (like locking any about:config Preference from Mozilla.cfg). Not sure if I succeeded to explain clearly..
