Tails 3.0 Live Boot ISO



Tails is a live system that aims to preserve your privacy and anonymity. It helps you to use the Internet anonymously and circumvent censorship almost anywhere you go and on any computer but leaving no trace unless you ask it to explicitly. It is a complete operating system designed to be used from a DVD, USB stick, or SD card independently of the computer’s original operating system.

Tails comes with several built-in applications pre-configured with security in mind: web browser, instant messaging client, email client, office suite, image and sound editor, etc.

Tails is a live operating system, that you can start on almost any computer from a DVD, USB stick, or SD card. It aims at preserving your privacy and anonymity, and helps you to:

• use the Internet anonymously and circumvent censorship;
• all connections to the Internet are forced to go through the Tor network;
• leave no trace on the computer you are using unless you ask it explicitly;
• use state-of-the-art cryptographic tools to encrypt your files, emails and instant messaging.

New in version 3.0

We are especially proud to present you Tails 3.0, the first version of Tails based on Debian 9 (Stretch). It brings a completely new startup and shutdown experience, a lot of polishing to the desktop, security improvements in depth, and major upgrades to a lot of the included software.

Debian 9 (Stretch) will be released on June 17. It is the first time that we are releasing a new version of Tails almost at the same time as the version of Debian it is based upon. This was an important objective for us as it is beneficial to both our users and users of Debian in general and strengthens our relationship with upstream:

  • Our users can benefit from the cool changes in Debian earlier.
  • We can detect and fix issues in the new version of Debian while it is still in development so that our work also benefits Debian earlier.

This release also fixes many security issues and users should upgrade as soon as possible.


New features

New startup and shutdown experience

  • Tails Greeter, the application to configure Tails at startup, has been completely redesigned for ease of use:
    • All options are available from a single window.
    • Language and region settings are displayed first to benefit our international audience.
    • Accessibility features can be enabled from the start.
  • The shutdown experience has also been redesigned in order to be:
    • More reliable. It was crashing on various computers with unpredictable results.
    • More discrete. The screen is now totally black to look less suspicious.

    Technically speaking, it is now using the freed memory poisoning feature of the Linux kernel.

Polishing the desktop

  • We switched to the default black theme of GNOME which has a more modern and discrete look.


Tails 3.0 benefits from many other small improvements to the GNOME desktop:

  • Files has been redesigned to reduce clutter and make the interface easier to use. Several new features have been added, such as the ability to rename multiple files at the same time and the ability to extract compressed files without needing a separate application.
  • The notification area has been improved to allow easy access to previous notifications. Notification popups have also been repositioned to make them more noticeable.
  • Shortcut windows have been added to help you discover keyboard shortcuts in GNOME applications.For example, press Ctrl+F1 in Files to display its shortcut window.


Security improvements in depth

  • Tails 3.0 works on 64-bit computers only and not on 32-bit computers anymore. Dropping hardware support, even for a small portion of our user base, is always a hard decision to make but being 64-bit only has important security and reliability benefits. For example, to protect against some types of security exploits, support for the NX bit is compulsory and most binaries are hardened with PIE which allows ASLR.
  • Update Tor Browser to 7.0 (based on Firefox 52 ESR) which is multiprocess and paves the way to content sandboxing. This should make it harder to exploit security vulnerabilities in the browser.

Major upgrades to included software

  • Most included software has been upgraded in Debian 9, for example:
    • KeePassX from 0.4.3 to 2.0.3
      Your password database will be migrated automatically to the new format of KeePassX 2.
    • LibreOffice from 4.3.3 to 5.2.6
    • Inkscape from 0.48.5 to 0.92.1
    • Audacity from 2.0.6 to 2.1.2
    • Enigmail from 1.8.2 to 1.9.6
    • MAT from 0.5.2 to 0.6.1
    • Dasher from 4.11 to 5.0
    • git from 2.1.4 to 2.11.0
