Thunderbird for Mac: 102.5.0 Mac OS: Ventura 13.0.1 On Mac OS 13 (Ventura), Thunderbird lists Mac OS X Address Book but it is empty. On Mac OS 12 (Monterey), Thunderbird can see (under the same entry) all my contacts (iCloud and on my Mac). On Monterey: Mac OS System Setting: Security & Privacy > Contacts has Thunderbird as item that can receive permission to read the Contacts on the system. On Ventura: Thunderbird is no longer listed on Ventura in the same entry. I have re-installed Thunderbird after upgrading to Ventura. But that has not helped.
