Review for CardBook by RagusJohn
Rated 5 out of 5 stars
Great product and ideal for sorting messy address books and syncs with Google Contacts easily. After Thunderbird upgrade to 102, it was the only add-on I could find that managed duplicate contacts. Recommend it to anyone who is a converted Thunderbird user. Philippe also provieded fantastic support very rapidly.
This review is for a previous version of the add-on (83.5).To create your own collections, you must have a Mozilla Add-ons account.
