Comment (by cypherpunks):

 The update process will make a backup '''copy''' of the entire Tor Browser
 $HOME directory, i.e. "<install-dir>/Browser".  This includes things like
 the "Downloads" dir, which can be quite large.  After a successful update
 the backup ("<install-dir>/Browser.bak") is removed.

 Making a copy of '''everything''' seems unnecessary, makes the update
 process much lengthier, and renders this problem more likely.
