How to Log in to Thunderbird on Desktop and Mobile

If you are using Mozilla Thunderbird, signing in to your email account is simple once you understand how the login system works across devices. Unlike traditional email services, Thunderbird does not use a browser-based login page. Instead, you add your email account inside the application, whether on desktop or mobile.
