+ * NOTE: "about:newtab" will always result in a default newtab page, and never an overridden URL.

+ * Access patterns:

+ * The behavior is different when accessing the service via browser chrome or via redirector
+ * largely to maintain compatibility with expectations of add-on developers.
+ *
+ * Loading a chrome resource, or an about: URL in the redirector with either the
