Warning for Tor and Firefox Users: Update Your Browser to Solve Anonymity Threats

You must update the Tor Browser to version 15.0.10 and Firefox following a major security flaw. This flaw allowed the browser to store unique technical data for each user, potentially enabling the unique identification of the browser user. This security flaw occurred even in private browsing windows.

We recommend that our readers update their browser versions as soon as possible, especially Tor, to resolve this security issue.

If you are a Tails user, you should update to the newest version (7.7) and then Tor Browser will be automatically updated.
