1389399 - Enigmail doesn't work in Thunderbird 56 beta, with "NS_ERROR_UNEXPECTED: Component returned failure code: 0x8000ffff (NS_ERROR_UNEXPECTED) [nsIXPCComponents_Utils.import] mime.jsm:16"

Status: RESOLVED INVALID

(Thunderbird :: General, defect)

Description

[Daniel Holbert [:dholbert]]

I was just upgraded to Thunderbird 56, and it seems this made Enigmail stop working.

My encrypted emails are no longer decrypted -- and if I try to interact with Enigmail UI, it doesn't do anything and triggers various warnings in my Ctrl+Shift+J Browser Console.

At startup, I see this in Browser Console:
NS_ERROR_UNEXPECTED: Component returned failure code: 0x8000ffff (NS_ERROR_UNEXPECTED) [nsIXPCComponents_Utils.import]  mime.jsm:16
Contract ID '@mozilla.org/enigmail/cline-handler;1' was registered as a command line handler for entry 'cline-enigmail', but could not be created.
NS_ERROR_UNEXPECTED: Component returned failure code: 0x8000ffff (NS_ERROR_UNEXPECTED) [nsIXPCComponents_Utils.import] mime.jsm:16

Note: the line referenced there (mime.jsm:16) is for this line of source code
> Components.utils.import("resource://gre/modules/jsmime.jsm"); /*global jsmime: false*/

If I click the Enigmail menu (on Thunderbird's menu toolbar), the menu opens, but I see this appear in my Browser Console:
TypeError: Enigmail.msg is undefined[Learn More] messenger.xul:1:1

And then if I choose "Setup Wizard" or "Preferences" from its menu, I see this appear in my Browser Console:
ReferenceError: EnigmailWindows is not defined[Learn More]  messenger.xul:1:1

Note: I am on the thunderbird "beta" channel (hence getting 56 as an update this week).

Also, https://addons.mozilla.org/en-US/thunderbird/addon/enigmail/ indicates that the add-on is expected to work with "52.0 - 56.0".

Also, I was running the latest Enigmail release version (which I believe was 1.9.8.1) when I first encountered this bug -- and I've tried installing the add-on's "development channel" version, 1.9.8b1 -- that's what I was actually using when I copypasted Browser Console contents for comment 0 here. (But I think the latest release version behaves the same.)  (I think the development version might also be older than the release, too, based on its version number -- not sure.)

Patrick, have you encountered any issues like this with Thunderbird 56 beta?  I'm on Linux and I don't have any other Thunderbird add-ons installed, for what it's worth.

Patrick is aware of this and has fixed it in his Nightly build.

FYI, this
  Components.utils.import("resource://gre/modules/jsmime.jsm");
should be
  Components.utils.import("resource:///modules/jsmime.jsm");

Closing the bug since it's an add-on problem.

I updated the compatibility info on AMO; Enigmail 1.9.8.1 is no only compatible with TB up to 55.0.

Thanks to you both!

I can confirm that this issue is fixed in the Enigmail nightly build, which is available here:

Note that the "Development version" section (with v1.9.8b1) still says that version is compatible up to 56.
  https://addons.mozilla.org/en-US/thunderbird/addon/enigmail/

(See attached screenshot)

Not sure if that's easy to edit or not, but if it is easy, that'd be worth fixing as well.  (Enigmail users on Thunderbird Beta will likely check that section when they see that the current release is unsupported for 56)
