A new version of *Thunderbird* is released in Debian shortly after each Tails release, 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 As a consequence, until Tails 7.5 (February 2026), the version of *Thunderbird* in Tails was almost always outdated, with known security vulnerabilities.

Sites often have a feed icon <i class="fa fa-rss"></i> that points to their
RSS or Atom feed.

If a site has no feed icon, right-click on the home or news page of the site in *Tor Browser*
and select **View Page Source** in the shortcut menu. In the source of the
page look for a link of type *application/rss+xml* or
*application/atom+xml*. Not all sites have a news feed.

<p><i>GnuPG</i> and <i>[[Kleopatra|encryption_and_privacy/kleopatra]]</i>
allow you to work with OpenPGP encrypted text and files. Consider using
<i>Kleopatra</i> instead of <i>Thunderbird</i> if you want to exchange encrypted text and files, but
not by email.</p>

<p>The OpenPGP keys stored in <i>GnuPG</i> and <i>Kleopatra</i> are separate from the keys
stored in <i>Thunderbird</i>.</p>

In *Thunderbird*, OpenPGP private keys are not protected by a passphrase. That's why we recommend that you set up a Primary Password.

With a Primary Password, your private key is encrypted in your *Thunderbird* profile and is only unlocked while *Thunderbird* is running. If your *Thunderbird* profile is stored in your Persistent Storage, then your private key is encrypted twice: once by *Thunderbird* in your profile and a second time by the encryption of the Persistent Storage.

If you already have an OpenPGP private key outside of *Thunderbird*, follow the instructions below to export it from *GnuPG* and import it into *Thunderbird*.

In the right pane, click the **Add Key…** button.

Click the **Select File to Import…** button and choose the private key that your exported from *Kleopatra*.

In the left pane, identify the account for which you want to create a new OpenPGP private key and choose **End-to-End Encryption**.

In the **Add a Personal OpenPGP Key** dialog, choose **Create a new OpenPGP Key**.

*Thunderbird* warns you if you miss the key of some of the recipients
or if you still have to accept some of their keys.

Choose **Security**&nbsp;▸ **Key Assistant** to see the keys of the
receipts and solve any issue.
