Address Books- I can't see or access them
Hi, I'm on a Mac, OS 10.15.7, using Thunderbird 78.7.1 (64-bit). Recently my Address Books disappeared from view. I can only see a list of all contacts in all address books. I cannot find a setting that allows me to see the 10 individual address books that I've set up over the years. If I ask to create a 'new' address book, I can see a listing of my other address books by I cannot access them. Can anyone help?
