I want to use Thunderbird for my email and not Verizon. About a month ago, Thunderbird just popped up on our computer with my email account and I enjoyed using it, but after a computer restart I can't seem to log on and when I put in my email to have the password sent to my verizon account (which is not a user friendly format) nothing comes through?? I have no idea how it appeared originally and how to get it back.
