My Time Machine backups often consist of Firefox's places.sqlite file (which, as I understand it, contains both history and bookmarks) and little else. When I clear my browsing history the file shrinks by about 80%. I think I have the following options:

  1. Live with it
  2. Exclude places.sqlite from being backed up and risk losing my bookmarks
  3. Tell Firefox not to track history

Is there another option under which I track history without burning space to back it up?

BTW, running sqlite vacuum helps some, shrinking places.sqlite by about a factor of two. The command is sqlite3 places.sqlite "vacuum;".

Set Firefox to auto-export your bookmarks on close to bookmarks.html in your profile and then exclude places.sqlite from being backed up.
