Tails 4.8 Anonymity Linux Based OS Released

Tails OS

Tails is a portable LIVE operating system that protects your privacy and helps you avoid censorship.

LEAVE NO TRACE. Tails uses the Tor network to protect your privacy online. It is based on Debian GNU/Linux.

What is in TAILS 4.8 OS version?

Tails disabled the Unsafe Browser by default and clarified that it can be used to deanonymize you.

An attacker could exploit a security vulnerability in another application in Tails to start an invisible Unsafe Browser and reveal your IP address, even if you are not using the Unsafe Browser.

For example, an attacker could exploit a security vulnerability in Thunderbird by sending you a phishing email that could start an invisible Unsafe Browser and reveal them your IP address.

Such an attack is very unlikely but could be performed by a strong attacker, such as a government or a hacking firm.

Tails includes:

  • Tor Browser with uBlock, a secure browser and an ad-blocker.
  • Thunderbird with Enigmail, for encrypted emails.
  • KeePassXC, to create and store strong passwords.
  • LibreOffice, an office suite.

This is why we recommend that you:

  • Only enable the Unsafe Browser if you need to log in to a captive portal.
  • Always upgrade to the latest version of Tails to fix known vulnerabilities as soon as possible.
  • Added a new feature of the Persistent Storage to save the settings from the Welcome Screen.

This feature is beta and only the additional setting to enable the Unsafe Browser is made persistent. The other settings (language, keyboard, and other additional settings) will be made persistent in Tails 4.9 (July 28).

Changes and updates

  • Update Tor Browser to 9.5.1.
  • Update Thunderbird to 68.9.0.
  • Update Linux to 5.6.0. This should improve the support for newer hardware (graphics, Wi-Fi, etc.).

Fixed problems

  • Fix the Find in page feature of Thunderbird.
  • Fix shutting down automatically the laptop when resuming from suspend with the Tails USB stick removed.
  • Notify always when MAC address spoofing fails and the network interface is disabled.
  • Fix the import of OpenPGP public keys in binary format (non armored) from the Files browser.

Tails 4.8 Change logs

Security fixes

  • Allow to disable the Unsafe Browser in the Welcome Screen. The Unsafe Browser can be used by exploits to deanonymize the Tails user.
  • Upgrade Tor Browser to 9.5.1-build2.
  • Thunderbird:
    Upgrade to Thunderbird 68.9.0 (DSA-4702).
    Disable unsafe MX automatic configuration method
    Disable unsafe MS Exchange automatic configuration method.
  • Upgrade Linux kernel to linux-image-5.6.0-2 at 5.6.14-2
  • Upgrade gnutls28-based packages to 3.6.7-4+deb10u4 (DSA-4697).
  • Upgrade intel-microcode to 3.20200609.2~deb10u1 (DSA-4701).


– Trigger emergency shutdown on resume when the boot device was removed while suspended.
– Thunderbird: make searching in messages (Find bar and Find in This Message) work again.
– Ensure Mac Spoofing Panic messages will be correctly displayed. udev may close child processes when a process associated with a rule (/etc/udev/rules) terminates so we wait for those processes before exiting.
– Wrap `seahorse-tool –import` so it is handled by `gpg –import`. This makes importing binary keys via GNOME
Files integration possible again.

Minor improvements and updates

– Upgrade to tor
– Upgrade LibreOffice to 1:6.1.5-3+deb10u6.
– Upgrade VirtualBox guest modules to 6.1.10-dfsg-1.
– Append Unsafe Browser setting to WhisperBack debug info.
