After filling this in and authorizing thunderbird to access your e-mails, your account should be set up and thunderbird should start fetching e-mails from your inbox. Thunderbird should auto-detect all the relevant parameters, and then an external webview should pop up to prompt for your e-mail address (it's not auto-filled, that's a separate issue that's also known upstream) and your password. In a clean environment, launch thunderbird and add an existing gmail account.

This has been fixed upstream and is tracked by https:/ /bugzilla. A recent server-side change with google e-mail accounts (gmail) means that thunderbird consistently fails to authenticate, prompting for the user's e-mail address and password over and over, without ever succeeding.
