This release is an emergency release to fix important security vulnerabilities in Tor Browser.

Changes and updates

• Update Tor Browser to 15.0.11, which fixes several vulnerabilities in Firefox 140.10.1.

We are not aware of these vulnerabilities being exploited in practice until now.

• Update Thunderbird to 140.10.0.

• Stop making it possible to start our ISO images from a USB stick.

Since 2019, we recommend USB images to start Tails from a USB stick, which is by far the most common way of running Tails.

We still distribute ISO images to start Tails from a DVD or in a virtual machine. Until now, these ISO images worked on USB sticks as well, but provided a degraded experience without automatic upgrades or Persistent Storage.

Our ISO images no longer work on USB sticks to save a few megabytes and prevent confusion for people who use USB sticks.

For more details, read our changelog.

Get Tails 7.7.1

To upgrade your Tails USB stick and keep your Persistent Storage

• Automatic upgrades are available from Tails 7.0 or later to 7.7.1.

• If you cannot do an automatic upgrade or if Tails fails to start after an automatic upgrade, please try to do a manual upgrade.

To install Tails 7.7.1 on a new USB stick

Follow our installation instructions.

The Persistent Storage on the USB stick will be lost if you install instead of upgrading.
