Rated 2 out of 5 stars

after deactivating/activating Cardbook just to send one mail the contacts (or better said the addressbooks) are lost (remote addressbook on Synology). With 95.3. categories and mail sending is not working.

This review is for a previous version of the add-on (95.3). 

after the available 95.5, a new version is instance of approbation which fix most the known bugs (95.6 here :https://addons.thunderbird.net/fr/developers/addon/cardbook/versions/2491083)
