Tails 7.9 Is Here: Better Tor Browser and Firmware Support for Anonymity

If you rely on Tails for private browsing or sensitive communications, the latest release brings a few concrete improvements worth knowing about. Tails 7.9, published on June 18, 2026 by Linuxiac, updates the Tor Browser and includes firmware fixes that can affect both security and hardware compatibility. Here’s what changed and how to update.

What Happened

The Tails team released version 7.9 about a month after version 7.8, which had removed the Thunderbird email client. The main changes in 7.9 are:

  • Updated Tor Browser: The new version brings the latest Tor Browser release, which includes upstream security fixes and improved anonymity protection. The exact version number isn’t detailed in the release notes, but the update follows the usual pattern of aligning with the latest Tor Browser stable.
  • Firmware updates: Tails 7.9 includes newer firmware for hardware components. These are mostly about fixing security vulnerabilities and improving support for newer devices, especially Wi-Fi and graphics chipsets.

No major new features were added. This is a maintenance release focused on keeping the existing privacy protections current.

Why It Matters

For anyone using Tails as a daily privacy tool, staying on the latest version reduces the risk of being deanonymized through known browser exploits. Tor Browser updates often patch weaknesses that could allow an attacker to break anonymity. The firmware updates matter because outdated firmware can leak information about your hardware or introduce stability problems that might compromise your session.

The previous version, Tails 7.8, had already strengthened Secure Boot handling and removed Thunderbird (which the team considered a potential attack surface for email-based threats). Tails 7.9 builds on that by addressing lower-level firmware issues.

One thing to note: Tails 7.7 added alerts when a Secure Boot certificate was about to expire, and 7.7.3 was an emergency release for the “Dirty Frag” vulnerability. So this update is part of a consistent pattern of incremental improvements rather than a major overhaul.

What Readers Can Do

Upgrade from an older version

The simplest method is to update within Tails itself:

  1. Boot your current Tails system.
  2. Open the menu and select Applications → Tails → Tails Updater.
  3. Follow the on-screen instructions. The updater will download the new system image and apply it to your USB stick or SD card.
  4. Reboot into the updated system.

If you’re using persistent storage, it should carry over without problems. But it’s wise to back up your persistent volume before updating, just in case something goes wrong.

Do a fresh installation

If you prefer a clean start or are setting up Tails for the first time:

  1. Download the Tails 7.9 ISO from the official website (tails.net).
  2. Verify the download by checking the cryptographic signature against the Tails signing key. Instructions are on the download page.
  3. Use Etcher or the Tails Installer to write the image to a USB drive (at least 8 GB).
  4. Boot from the USB and configure your persistent volume if needed.

After updating

  • Verify that your persistent storage is still accessible and that any custom settings (like additional software or bookmarks) are intact.
  • Check that the Tor Browser launch page shows the new version. If something looks off, try restarting the browser or rebooting.
  • Run the “Tails Greeter” to ensure Secure Boot alerts are still functioning if you need them.

Why Firmware Updates Are Critical for Anonymity

Most users think of Tails as just a Linux distribution that routes traffic through Tor. But the underlying hardware firmware also matters. Flaws in Wi-Fi or Bluetooth firmware could, in theory, be exploited to leak MAC addresses or other identifiers. By keeping firmware current, Tails reduces the chance that your hardware itself becomes a fingerprint. This is especially important if you’re using newer laptops or adapters that might have unpatched drivers.
