Excellent address book for Thunderbird. I use it to sync Thunderbird with my Nextcloud server on all my computers. It would be great if this extension replaced the current Thunderbird address book. The support for the CardBook extension by the developer is also very good.

This review is for a previous version of the add-on (55.2).
