  1. The Tor Browser, which contains a Tor daemon that runs concurrently with the Tor Browser. Click on the link and select the package that fits your operating system, then download and install on your computer.
  2. Important: Please configure the tor daemon of the Tor Browser as recommended in our Tor Browser configuration manual. The connection security is similar to those in a Tor Hidden Service scenario but avoids Onion-host names and therefore, the SSL certificate errors experienced before.
  3. The e-mail client Mozilla Thunderbird with the add-on Tor Birdy installed. If you are already using Thunderbird as your e-mail client, simply open the built-in Add-On manager, search for Tor Birdy, and install. Linux users can also use their system's package manager to install the related package xul-ext-torbirdy.

Note that the above combination of using Thunderbird with the add-On Tor Birdy is the only solution currently recommended by for the anonymous management of e-mails via Tor Onion Router. We, too, will only support this particular software combination.

Mozilla Thunderbird Configuration

Install and configure all required software components as detailed above. Then start the Tor Browser first, before starting Mozilla Thunderbird. 

Please make sure the status bar at the bottom of the Thunderbird application window shows the status message TorBirdy Enabled: Tor.

For security reasons, the Tor Birdy add-on disables most parts of the software wizard for creating new e-mail accounts. You may still enter your e-mail address and password - however, the wizard will only ask whether to set up the account using either POP3 or IMAP as protocol.
