Comment (by teor):

 Replying to [comment:2 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.

 That would explain #18179, where I continued to make changes to the
 bookmarks after the updater had downloaded, only to see them reverted once
 it was applied.
