I used and recommended CardBook for years. This year, it has not kept up with the frequent Thunderbird updates. The most recent CardBook version, 107.2, will not sync with Google Contacts, and I cannot even make local changes--when I open an entry, all of the fields are blank. I liked CardBook's ability to display Google Contact Notes . I used one or two words to remind me where I knew each person. The Thunderbird address book will not display Notes, but it occurred to me that I could move Notes in Google Contacts to the Company field, and Thunderbird address book will display that field. Obviously, Thunderbird developers know what changes are coming and they don't have to release changes until they are checked. With CardBook, Philippe doesn't have much notice of Thunderbird changes, making it hard to keep CardBook functioning. He has my sympathy, and I wish him well, but it's time for me to switch to the Thunderbird address book.
