When starting <span class="application">Thunderbird</span> for the first time, an assistant appears to guide you through the process of configuring <span class="application">Thunderbird</span> to access your email account.
- With <span class="guilabel">IMAP</span>, <span class="application">Thunderbird</span> constantly synchronizes with the server and displays the emails and folders that are currently stored on the server. IMAP is better suited if you access your emails from different operating systems.
- With <span class="guilabel">POP</span>, <span class="application">Thunderbird</span> downloads the emails that are in the inbox on the server and possibly deletes them from the server. POP is better suited if you access your emails from Tails only and store them in the Persistent Storage.
