Tails 7.9 Is Here: Tor Browser Update and Firmware Fixes Boost Anonymity

The latest version of the anonymous operating system Tails (The Amnesic Incognito Live System) arrived on June 18, 2026. Tails 7.9 brings an updated Tor Browser and several firmware improvements. For anyone who relies on Tails for private browsing, journalistic work, or everyday anonymity, this release is worth installing as soon as possible.

Here is what changed, why it matters, and how to update.

What Happened

Tails 7.9 is a point release that focuses on keeping core components current. The most visible change is the inclusion of a newer Tor Browser (the exact version number had not been confirmed at the time of writing, but the previous release used Tor Browser based on Firefox ESR 128). Upgrading Tor Browser addresses any recently discovered vulnerabilities in earlier builds and ensures that the browser’s anti-fingerprinting measures remain effective against modern tracking techniques.

The release also includes firmware updates. Tails ships with a selection of non-free firmware blobs to support Wi-Fi, graphics, and other hardware. Keeping this firmware up to date mitigates potential security flaws in device drivers—especially critical for wireless networking, which is often a weak link in anonymity setups.

Other changes appear minimal. The release notes (available on the official Tails website) may list bug fixes or dependency updates, but no major new features were announced. This is consistent with Tails’ philosophy of stability over novelty.

Why It Matters

For privacy and security software, staying current is not optional. An outdated Tor Browser can leak identifying information; old firmware can leave hardware open to exploits. Tails 7.9 reduces those risks.

The update follows a string of recent releases: Tails 7.8 removed the Thunderbird email client and updated Tor Browser; Tails 7.7.3 was an emergency fix for the Dirty Frag vulnerability. The pattern shows that the development team takes reported issues seriously and ships patches regularly.

For journalists and activists who depend on Tails for sensitive work, running an older version increases the chance that a browser exploit or firmware bug could compromise anonymity. Using the latest version is a straightforward way to maintain the strongest protection available.

What Readers Can Do

Upgrading to Tails 7.9 is straightforward.

  1. If you already have Tails installed (version 7.0 or later), you can upgrade automatically. Boot Tails, set an administration password, and choose “Upgrade” from the start menu. The system will download and apply the update. Automatic upgrades preserve your persistent storage.

  2. If you are installing from scratch or using an older version that cannot upgrade automatically, download the new ISO from the official Tails website. Verify the download using the provided signature and checksum, then create a bootable USB drive using Etcher, Rufus, or the Tails Installer.

  3. If you use Tails from a DVD or SD card, create a new one with the latest image. There is no upgrade path for read-only media.

If you encounter any issues, the Tails documentation includes troubleshooting steps for common upgrade problems. As of this writing, no regressions had been reported for 7.9, but as with any release, occasional compatibility issues with certain hardware may arise.
