Tails 2.4 – The Amnestic Incognito Live System
Tails is a live system that aims to preserve your privacy and anonymity. It helps you to use the Internet anonymously and circumvent censorship almost anywhere you go and on any computer but leaving no trace unless you ask it to explicitly.
It is a complete operating system designed to be used from a DVD, USB stick, or SD card independently of the computer’s original operating system. It is Free Software and based on Debian GNU/Linux.
Tails comes with several built-in applications pre-configured with security in mind: web browser, instant messaging client, email client, office suite, image and sound editor, etc.
New features
-
We enabled the automatic account configuration of Icedove which discovers the correct parameters to connect to your email provider based on your email address. We improved it to rely only on secure protocol and we are working on sharing these improvements with Mozilla so that users of Thunderbird outside Tails can benefit from them as well.
