Great extension, but the defaults could be better Rated 4 out of 5 stars

This extension works very well, but I dislike the default of plain text signing. It's a great way to annoy everyone on a mailing list... It seems the rationale is to have better support for receivers using bad mail clients, but I doubt they're verifying emails via copy-paste if they can't be bothered to use another client.

Qu'apporte Enigmail ? Rated 3 out of 5 stars

J'ai du mal à voir ce qu'apporte Enigmail par rapport aux options de base de Thunderbird:
.Chiffrer ce message
.Signer numériquement ce message


It can't install in FossaMail Rated 1 out of 5 stars

Alright, I gave it a look and it can't install in FM 24.2.0b1- but it could install in TB 24.2.

I also went to the support page which then insisted on creating an account at Sourceforge. I no longer trust SF due to it's recent changes and the account also could not be created no matter how much I juggled things around. Even if that did work that is an awful lot of steps!

If it can be modified to work correctly I will come back and write a better review. Until then it is 1*

Fonctionne parfaitement sous Win7 ou Fedora19.
Dommage que ça ne fonctionne qu'en texte brut, mais on va pas chipoter :)

Nearly perfect Rated 5 out of 5 stars

It's a wonderful tool and essential for secure mail sending. It is easy to use under Linux and Windows upto Win7.It doesn't work with Thunderbird 24.1.1 and Windows 8.But at least it is better to do without Win 8 than Enigmail!
Hello Patrick, unfortunately I don't see a possibility to answer to your statement directly, so I would like to tell you in this way, that I made the experiences with Enigmail and Thunderbird in Win8 by my self. I have screenshots, which show, that Enigmail 1.9 is not compatible to Thunderbird 24.1.1
I run several Linux systems as well as Win 7/8/8.1, but it is only in Win 8 and 8.1. not compatible.
I don't know why.

Why would Enigmail not work on Windows 8? I cannot see any reason for this, and I know of many users who use this combination successfully.

Mandatory addon for Thunderbird. Works flawlessly with the newest version. If you value your privacy, this is your best choice for protecting yourself.

Searching the content of encrypted mails is not possible Rated 2 out of 5 stars

Encryption and decryption of mails works perfectly but searching for a content in the mails is not possible any more. With this restriction it is not possible for me to use enigmail.

Not compatible with Thunderbird 12.0.1.? Rated 1 out of 5 stars

Just wanted to install the latest version but it got this message: "Enigmail could not be installed because it is not compatible with Thunderbird 12.0.1." Do you have any plans to make Enigmail compatible? Many thanks!

This review is for a previous version of the add-on (1.5.2). 

Thunderbird 12 is not quite recent anymore and has known security bugs. I'd recommend you upgrade to the current stable version of Thunderbird - v17. Alternatively, you'll find a working version of Enigmail by clicking on "view other versions". You would need Enigmail v1.4.2 for Thunderbird 12.

Does not work Rated 3 out of 5 stars

This plugin isn't working. Whenever I "encrypt" my e-mails, the recipient - when asked to enter the passphrase - is able to just view them by just closing the window. This add-on is either not working or I'm doing something terribly wrong. Hm...

Enigmail is an excellent and classic add-on! Rated 5 out of 5 stars

Don’t be put off by the review below! With a willingness to learn a little about encryption and secure and trusted communication, and a bit of common sense, you can set up encrypted e-mail on Thunderbird practically by selecting the defaults.

As pointed out in the details above, you will need GnuPG, so the first thing to do is go to and download GPG4Win (this is for Windows, obviously). After installing it, you will find a folder on your desktop containing the GPG4Win Compendium PDF. This contains an excellent simple explanation of the principles behind secure and trusted communication, and why you should care about it. I have put the PDF on my tablet and read it repeatedly. You have to know a little about the fundamentals before you can understand what the e-mail setup is actually about.

Now start Thunderbird, and you should see an OpenPGP menu item. There is a setup wizard to get you started. I just selected defaults where I wasn’t sure, and had the whole thing set up in less than half-an-hour. Nothing to do with the command line. It was simpler than setting up Outlook to do the same. But you have to know what’s going on, so read the Compendium first.

If all you want is to send someone an encrypted message once a month, I recommend the Simple Text Encryptor tool from here:; you just copy and paste your message into the top box and it comes out encrypted to AES 128-bit standard at the bottom – not quite as simple as pressing “E” but not far off!

You don’t need to attend a seminar to use this tool, but you do need to be prepared to learn something new, and to do a little more than press E.

We may not take it particularly seriously at the moment, but there are countries where tools like this are an absolute necessity to maintain the human right of privacy, so it’s great that they are available free. And the way the UK and US governments are heading, we may need such tools sooner than we think. Thank you, Patrick Brunschwig and the GnuPG team!

Finally, as a REVIEWER, you NEED to be AWARE that if you type INANE reviews with LOTS of CAPITALS, and “inappropriate use” of quotation marks, and odd *placement* of *star* symbols, it’s going to REALLY HACK some people OFF, as well as GIVING them SERIOUS DOUBTS about your LEVEL of MATURITY. Verb. Sap.

Impossibly complicated for those unfamiliar with PGP Rated 3 out of 5 stars

I suppose if you're using PGP already, use it on the command line, this does something to facilitate its use in Thunderbird?

The fact is that I had to stop looking at this add-in with "PGP servers" option.

There is simply no way in the name of anything that I'd ever be able to convince anyone to use this without taking a SEMINAR on encryption and PGP.

Add to this that most of people (in population numbers, not by emails) who would *like* to send out an encrypted email would probably want to do it MAYBE ONCE OR TWICE A MONTH TOPS.

I want to send my computer-stupid friend a single message ENCRYPTED, but this is RIDICULOUS. It would be easier to type up a text file and put it in an encrypted Zip file.

Do you know how STUPID this whole thing is in this "computer age" of iPhones and iTablets? There should be an "E" button BUILT IN to Thunderbird and THAT'S IT.

The closest I've come is some "service" which wants $10 a month FROM EACH OF USER to use OPEN SOURCE software so we can send a HANDFUL of messages to each other a YEAR.

THIS is why no one uses encryption.

Great for original TB Rated 5 out of 5 stars

Update: Thanks for the quick reply, appreciated. Postbox wrote: "contact the original add-on developer directly or disable the add-on". So I had hope they did not lie. Anyway thanks. Giving you for the TB version a 5/5

The Postbox version of Enigmail are provided by Postbox. It's not the fault of Enigmail that Postbox doesn't publish their source code, such that official releases of Enigmail don't work on Postbox ...

Seriously, Mozilla should integrate this plugin into mainline.

Should be a must have feature beside default S/MIME Rated 4 out of 5 stars

Having a S/MIME certificate is hard but having a GnuPG keypair is easy. On the other hand using OpenPGP signing without using PGP/MIME messes the email message for those who doesn't have OpenPGP compatible client.
So the best part of this add-on is "OpenPGP Signing + PGP/MIME"
