For what it's worth, I do this too. I expect our updater will eventually
use this mechanism underneath, too.

The most annoying result is that you lose your custom pref settings, due
to https://trac.torproject.org/projects/tor/ticket/3944. I find this
annoying because I actually like having local TBB browsing history.

On the plus side, any custom Firefox extensions you have in your TBB do
stay active after updating this way (though the usual caveat about
choosing your extensions carefully to avoid leaks and fingerprinting
applies).
