New Release: Tails 7.5

by tails | February 26, 2026

Changes and updates

  • Update Tor Browser to 15.0.7.

  • Simplify the home page of Tor Browser.

  • Update the Tor client to 0.4.9.5.

  • Update Thunderbird to 140.7.1.

  • Install Thunderbird as additional software to improve its security, if you have both the Thunderbird Email Client and Additional Software features of the Persistent Storage turned on.

Until Tails 7.5, a new version of Thunderbird was released by Mozilla only a few days after we released a new version of Tails. As a consequence, the version of Thunderbird in Tails was almost always outdated, with known security vulnerabilities.

By installing Thunderbird as additional software, the latest version of Thunderbird is installed automatically from your Persistent Storage each time you start Tails.

If the Thunderbird Migration dialog below appears when you start Thunderbird , it means that Tails successfully installed Thunderbird as additional software.

  • Include the language pack for Mexican Spanish in Thunderbird in addition to the language pack for Spanish from Spain.
