Thanks for the info. While your solution fixes the error that crops up
in SeaMonkey js. This doesn't protect against random extensions using
the for...in operator. Since in the Firefly code there is only one
consumer (tree.xbl) for the inArray method, I've moved the code into the
tree.xbl as an additional method of the XBL widget.
