Enigmail is a seamlessly integrated security add-on for Interlink Mail & News and Postbox. Mozilla Thunderbird is supported until version 68. Enigmail allows you to use OpenPGP to encrypt and digitally sign your emails and to decrypt and verify messages you receive. Enigmail is free software. Depending on the configuration, Thunderbird with Enigmail will try to automatically download the public keys of people who send you signed and encrypted messages so that they are available for you to use. This can only happen if others have also uploaded their public keys to a key server.

1. Enigmail Thunderbird Add On
2. Enigmail Thunderbird

1. To install Enigmail in Thunderbird, use right click 'Save Link as.' To save the extension locally. Then navigate to the Thunderbird menu Tools Addons and click on the small Tools button in the upper right corner and then on Install Add-on From File.
2. It seems that the Enigmail extension was updated today in my Ubuntu desktop machine. The version is now 'Enigmail 2.1.8'. However, after Thunderbird starts (and a few seconds pass) Thunderbird freezes. I had to kill Thunderbird from command line and start it in 'safe mode'.

  • 1.1Installing Enigmail on Fedora

Fedora Core includes Mozilla Thunderbird in the thunderbird package, and the mozilla-mail package for the Mozilla Suite email application. Thunderbird is the recommended Mozilla email application. This appears on your desktop as Applications > Internet > Thunderbird Email.

Mozilla products support extensions, plugins that add new features to the main application. The Enigmail extensions provide GPG support to email products from Mozilla. Versions of Enigmail exist for both Mozilla Thunderbird, and the Mozilla Suite (Seamonkey). Netscape software from AOL is based on the Mozilla products, and may also use this extension.

To install Enigmail on Fedora systems, follow the instructions given below.

Enigmail uses the term OpenPGP in menu items and options. GPG is an implementation of OpenPGP, and you may treat the terms as equivalent.
