Hi,
For whatever reason, cardbook index is not anymore automatically opened when TB is opened - 78.7.0 (32 bits)

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

have you got issues at Thunderbird startup (CTRL+SHIFT+J) ? (cardbook (at) cardbook.icu)
