This project was completely obsolete because Firefox does not support security models based on policies anymore.
Use site-specific permissions instead.
For enterprise use, Permissions Auto Regsiterer https://addons.mozilla.org/firefox/addon/permissions-auto-registerer/ will help you.
This is an extension for managing Site Policies, a security feature (, it's like IE's "security zones").
Firefox includes the feature secretly, but there is no UI. This package includes manager GUI and a context menu extension to set the site's policy easily.
