You can still install Thunderbird as additional software.mKd免费翻墙网
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.mKd免费翻墙网
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 As a consequence, until Tails 7.5 (February 2026), the version of Thunderbird in Tails was almost always outdated, with known security vulnerabilities.mKd免费翻墙网
By installing Thunderbird as additional software, the latest version of Thunderbird is installed automatically from your Persistent Storage each time you start Tails.mKd免费翻墙网
Fixed problems
