Enigmail 3.0

Released 2021-06-05, works with Interlink Mail & News 52.9 and Postbox 7.

Notable Changes

This release introduces a new backend that allows to use different OpenPGP implementations. Currently, OpenPGP.js (natively built into Enigmail) and GnuPG are supported. By default, if GnuPG is found and at least one private key is available in GnuPG, then GnuPG will be used for crypto-operations. If GnuPG is not found or seems unused, then OpenPGP.js will be used. OpenPGP.js is included in Enigmail and does not require any further downloads.

The OpenPGP.js implementation of Enigmail contains a very simple trust model. Any new key is trusted by default. If you don't want to trust a key, you can distrust it (which acts similarly to disabling a key in GnuPG). We might add something like TOFU in a future version of Enigmail, but that's not yet decided. If you require a more sophisticated trust model, you should use the GnuPG backend instead.

Future versions of Enigmail will support additional OpenPGP implementations, such as SOP. In particular, the current GnuPG backend that accessed gpg directly will be replaced with functionality that requires gpgme-json. Enigmail will no longer directly access GnuPG for crypto- functions.

Enigmail 2.0.7

Released 2018-06-13, works with Thunderbird 52.0 - 60.0 and SeaMonkey 2.46 - 2.55.

Notable Changes

This release addresses several critical security bugs.

Bugs fixed:

Spoofing of Email signatures I (CVE-2018-12020): GnuPG 2.2.8 fixed a security bug that allows remote attackers to spoof arbitrary email signatures via the embedded "--filename" parameter in OpenPGP literal data packets. This release of Enigmail prevents the exploit for all versions of GnuPG, i.e. also if GnuPG is not updated.
Spoofing of Email signatures II (CVE-2018-12019): The signature verification routine in Enigmail interpreted User IDs as status/control messages and did not correctly keep track of the status of multiple signatures. This allowed remote attackers to spoof arbitrary email signatures via public keys containing crafted primary user ids.
Mozilla crash bug 1423895: if Enigmail is installed on Thunderbird 60b7 together with the Add-Ons "CardBook", "QuickFolders" (and possibly other Add-Ons), then Thunderbird will crash as soon as an Enigmail-specific window is opened. This version implements a workaround for the Mozilla bug.

Enigmail 2.0.6

Released 2018-05-27, works with Thunderbird 52.0 - 60.0 and SeaMonkey 2.46 - 2.55.

Enigmail 2.0

Released 2018-03-25, works with Thunderbird 52.0 - 60.0 and SeaMonkey 2.46 - 2.55.

Notable Changes

The Encryption and Signing buttons now work for both OpenPGP and S/MIME. Enigmail will chose between S/MIME or OpenPGP depending on whether the keys for all recipients are available for the respective standard.
Support for Pretty Easy Privacy (p≡p) is implemented in Enigmail. p≡p is active by default for new users.
Support for the Autocrypt standard, which is now enabled by default. If Enigmail is used in the "classical mode" (with p≡p disabled) then Autocrypt is enabled by default.
Support for Web Key Directory (WKD) is implemented. Enigmail will try to download unavailable keys during message composition from WKD. If you use GnuPG 2.2.x, and your provider supports the Web Key Service protocol, you can also use Enigmail to upload your key to WKD.
The message subject can now be encrypted and replaced with a dummy subject, following the Memory Hole standard for protected Email Headers.
The keys on the keyring are automatically refreshed from keyservers at an irregular interval.
Enigmail was turned into a "restartless" addon. That is, once you installed Enigmail 2.0, subsequent updates will be installed without needing to restart Thunderbird.
Keys are internally addressed using the fingerprint instead of the key ID.
The minimum GnuPG version supported is now 2.0.16.
Cygwin-versions of GnuPG are no longer supported.
