AOL is telling me to upgrade Thunderbird for security reasons. two days ago I came here and found a question and answer concerning changing the incoming code (for lack of better wording term for how incoming emails). Then yesterday I decided that what AOL wanted was for me to make another account, which seemed easy to do. You guessed it now all my incoming emails are doubled ,I get two of every email sent to me from AOL. Did AOL want me to go and do a complete delete my thunderbird account and start over from scratch? I have too much files many that I save. So I have two problems. I have tried to change, delete one of my two accounts but cannot find them. I am sure that by now you realize I am not a computer nerd. Thank you for any help that can solve all my problems
