+By default thunderbird uses an address book called `Personal Address Book`.
+When using a remote address book which is synced the default address book is often not needed.
+It can be hidden by selecting `Edit` (if the top bar is not visible `Alt` can be pressed to display
+it), `Settings` and `Config Editor...`.
+In the config editor search for the value `ldap_2.servers.pab.dirType` and set the value from the
+default (which is `101`) to `-1` to hide the default address book.
