A new version of *Thunderbird* is released in Debian shortly after each Tailsrelease, because both *Tails* and *Thunderbird* follow the [[release calendar of *Firefox*|https://whattrainisitnow.com/calendar/]]. As a consequence, until Tails 7.5 (February 2026), the version of *Thunderbird* in Tails was almost always outdated, with known security vulnerabilities.

Tails also tries to install as additional software the language package that corresponds to the language of this Tails session, if it exists. To use *Thunderbird* in another language, see [[using *Thunderbird* in another language|thunderbird#language]].

*Thunderbird* will be reinstalled automatically every time you start Tails. Future installations will be much faster since *Thunderbird* is already downloaded to your Persistent Storage.
If the automatic configuration succeeds, you might have to specify which protocol to use to connect to your email provider, either **IMAP** or **POP**.
- With **POP**, *Thunderbird* 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.
