New Release: Tails 7.8

Changes and updates

• Update Tor Browser to 15.0.14.

• Remove Thunderbird.

You can still install Thunderbird as additional software.

If you have both the Thunderbird Email Client and Additional Software features of the Persistent Storage turned on, Tails automatically adds Thunderbird to your list of additional software.

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 As a consequence, until Tails 7.5 (February 2026), the version of Thunderbird in Tails was almost always outdated, with known security vulnerabilities.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

Fixed problems

• Fix multiple security vulnerabilities in the Linux kernel and haveged, that could allow an application in Tails to gain administration privileges.

For example, if an attacker was able to exploit other unknown security vulnerabilities in an application included in Tails, they might then use one of these vulnerabilities to take full control of your Tails and deanonymize you.
