When attempting to add a verizon.net email to thunderbird I ave filled out he boxes for name, email address, and password. The program auto fills settings. When I select "done" it opens a aol sign in window with my email address already filled in. when I select "next" ( to type my password), I get a message (in red) that says "please enable cookies in browser and sign in again". I then have to press my ecsape key to return to the account setup screen, That screen displays a message "unable to log in at server probably wrong configuration, username, or password" I have tried the setup with my regular password and a aol generated app password wit the same result, I also change my Firefox (my default browser) security settings to "custom" and enabled all cookies and got the same result. I am able to access my email account thru the AOL site and my iphone.
