Remove Thunderbird's (empty) Personal Address Book

Question

How is it possible to remove Thunderbirds Personal Address Book (PAB)? It's empty and I don't use it because I use Googles address book.

The respective file in my profile, abook.mab is not listed in the prefs.js so no solution based on altering the preferences works. It also had no success to remove or rename abook.mab.

Answer 1

In the extended configurations area set the value of "ldap_2.servers.pab.dirType" to -1
I found this solution also while searching for that, but do not remember whom to praise for that. Cudos.
