Rated 4 out of 5 stars

I agree with Alan. CardBook is a exceptional address book except when it is suddenly disabled by a Thunderbird update, which has happened twice this year. I don't know how much effort it is to keep CardBook compatible, and Philippe has been supporting it for a long time. If it is time to retire CardBook, I hope he will let us know.

This review is for a previous version of the add-on (106.2).
