My old email address no longer works. My new address is <@gmail.com> My old address was <@wisc.edu>. How do I change this in your system?

There is no Thunderbird system. Thunderbird is email client software running on your computer. You download Thunderbird and install it on your computer. Then add the details of your email account to it.

FYI: This is a public forum and posting personal info like your email addresses is not a very good idea.
