Yup. I used a somewhat different terminology here. It is important to
realize that the tree on the left hand side uses tree protocol methods
to determine what is displayed and what isn't, and what URLs the
displayed items have. The Mozilla tree should display the same items.
There is a difference between tpValues and objectValues.

Mind that you should be able to root the left hand tree on any Zope
folderish URL, like http://localhost/QuickStart/.
