Excellent point. This is a good argument for being able to unpack a new
TBB on top of the old one -- which I'm told usually works, but doesn't
always work, and that's a big problem.

Longer term, the right answer is to use the Firefox update mechanism in
TBB 3.0 to update, in place, only the parts that need updating.
