Thank you so much for your question. I assume you're referring to this tutorial. The first screen is the "homepage," if you will, of Thunderbird. This is what shows if you do not have your inbox selected. However, this screen is not needed for the tutorial. You can navigate to the setting by clicking your email address in the left-hand panel, then follow the rest of the instructions in the tutorial. If you need additional assistance, please reach out to our live support.
