The last version broke the Thunderbird and made it unusable. A desastre!! Now if activated I cannot send messages. I need to desactivate this extension to send messages. Looking for other extension to sync adreesbook.

This review is for a previous version of the add-on (95.2). 

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)
