 # XXX We'd like to add a context="_child" property to this toolbarbutton, but doing
 # so causes the context menu to show up for the textbox too, and subsequently crashes
 # the app on shutdown.  See bug 336662.

+# XXX We'd also like to specify the menupopup position as after_end, as well as 
+# probably adjusting its length to match that of the searchbar so the search 
+# engine icons line up, but that's prevented by inconsistent behavior of the 
+# popup position within a toolbarbutton.  See bug 336868.
