I upgraded to the lastest version of Thunderbird. It was asking for my password, and then hanging when I checked remember this password, or whatever it's called. I read somewhere here that someone had the same problem and stopped checking that. That works, but I have to put my password in every time. At any rate, I came on here for help and couldn't remember the password for here. I went through the steps to change my password, and now I've lost my address book in Thunderbird. How can I get it back? If I reinstall the older version will I get it back? Or is there something else I can do? I'm wishing at this point that I hadn't upgraded.
