Rated 5 out of 5 stars

A must-have for those who use vCard format contact lists!
One question: How do you add a URL for synchronization? When I go into "Preferences" and select the "Sync" tab, it will not allow me to type in the "Address books discovery" field, even after I tick the "Accounts" box.

UPDATE: Thanks much Philippe, that did the trick. Thanks again for a great add-on!

This review is for a previous version of the add-on (35.3).  This user has a previous review of this add-on.

Hi

right click on the left pane, then "Add New Address Book", then choose remote...
in CardBook preferences, sync tab, discovery groupbox, you will only see CardDAV accounts that were previously added.
