Rated 1 out of 5 stars

After 30 years of programming computers, I simply cannot get this thing to work. Importing an existing .VCF often fails. When it does succeed, categorizing the contacts results in duplication of the contact. Even deleting and reinstalling Cardbook does not help. This time the deletion is for good.

This review is for a previous version of the add-on (21.7). 

I'm very interested by your problems, may you email me a test case which is failing ? (cardbook.thunderbird@gmail.com)
