Rated 5 out of 5 stars
This extension creates separate address book that is not integrated with Thunderbird. It syncs well with my Gmail contacts, but Thunderbird cannot see or access this address book.
So, if I want to create an email filter in Thunderbird which looks in my address book, Thunderbird offers only its own empty address book as an option. It doesn't even see the new address book created by this extension that is synchronized with my Gmail.
Autocomplete of email addresses in the compose email window works properly though.
Is there a way to integrate the new address book with Thunderbird, so that Thunderbird can see it??? I looked at all the options, and there's nothing like that.
EDIT: Thanks to the developer who replied promptly and solved the issue!
For the filters, CardBook adds its own filters, look at the bottom of the drop down list... If you still have issues, email me : email@example.com ;)
