How is a NGT different from a Web browser?
NGT provides the foundation needed to build a browser interface, including a layout engine and a complementary set of browser components. However, NGT does not package all of these components alongside other interface modules in a coherent, user friendly Web browser application, such as Navigator. The Mozilla team will assemble the necessary components into a user friendly application. Third party ISVs will pick and choose the components they want to embed in their applications. Certain components are not provided as part of NGT, such as bookmarks, history, address book, etc.
