We use .cfg file in browser installation directory to set prefs or lock prefs for all users. We have lock pref that block any add-on installation in browser. But when logging in Firefox Account, all addons from "home PC", e.g., syncing with local PC where installation is disabled. How can we prevent that? Thank you.
