My previous computer's hard drive said it was failed. I copied off the thunderbird profile before it crashed. I bought a new computer. I restored the thunderbird profile. Within a few hours, the email and file folders revert to a 2014 data file any anything from that time forward does not appear. So I went in, uninstalled thunderbird, deleted all the thunderbird profiles and their files and put it back on again. Within a couple hours, it did it again.

So I again uninstalled thunderbird, searched everything thunderbird and deleted all I could and downloaded a fresh copy of thunderbird and then restored the profile again. Within about 30 minutes there are now three different default profiles for thunderbird. I don't know what else to do. The e-mail files aren't changed yet, but I'm waiting...... Are three supposed to be there, I would think not. I certainly didn't create them. Somebody know what to do??????
