From https://blog.torproject.org/blog/tor-browser-40-released

This release also features an in-browser updater, and a completely reorganized bundle directory structure to make this updater possible. This means that simply extracting a 4.0 Tor Browser over a 3.6.6 Tor Browser will not work.

Do this:

  1. Backup your bookmarks from 3.6.6 using the bookmark manager of Firefox.
  2. Remove TBB 3.6.6 completely.
  3. Unpack TBB 4.0.
  4. Start TBB 4.0.
  5. Import you bookmarks from the backup file.

Using add-ons other then the ones provided by TBB is not recommended.
