Just doesnt work Rated 1 out of 5 stars

If you download gnupg, sorry wrong version, if you rely on this s...t soft to download it, it doesnt. And no, no firewal or any other software running in background. Why to do something that is shit from the beginning?

Linux mint 17, problems with 1.9.2 Rated 3 out of 5 stars

To use it on Linux Mint: I'm using Enigmail add-on 1.8.2, Thunderbird 45.1.0. Enigmail 1.8.2 (installed by Synaptic). I've uninstalled seahorse-daemon, seahorse, keyring, gpgv2. I have installed gnupg, gnupg-agent, gnupg2. I've deleted in home hidden folders: .gnupg/ , .thunderbird/. Finally on terminal :

sudo nano ~/.gnupg/gpg-agent.conf

and add the line "use-standard-socket" (this will allow Enigmail to communicate with gpg-agent)

After reboot Enigmail in Thunderbird works.

HiDPI support missing Rated 4 out of 5 stars

Great tool but please add HiDPI icons for e-mail status indication. With 2x scaling factor (GNOME3) the icons look just too blurry and plus too old-school anyway.
With more and more high resolution displays out there, this is really a thing.

Saving a draft is always encrypted Rated 4 out of 5 stars

When I toggle encryption and signing off inside the compose message window and save the mail as draft, it's always encrypted.
Because I can't find an option for this behavior I guess it's a bug.

Edit:

thank you for the reply - this settings must have been added some time ago and I just didn't see it since then ...

This review is for a previous version of the add-on (1.9.1). 

That's a feature, not a bug. You can turn off encryption of drafts in the account settings under OpenPGP Settings.

Wonderful!
Lack of some options, but not critical

Viel zu kompliziert Rated 1 out of 5 stars

Ich will von 1000 Mails eine einzige verschlüsselt senden. Nach erheblichem Installationsaufwand - die Links in den Tutorisals sind zum Teil veraltet, man muss recherchieren, wo man GnuPG herbekommt - muss man JEDES MAL ein Passwort eingeben, wenn man Thuderbird startet. Die beiden ersten Versuche, verschlüsselte Mails zu senden, schlugen auch fehl. Der Empfänger konnte die Mails nicht öffnen. Bestimmt haben wir etwas falsch gemacht. Aber wenn man selbst als halbwegs erfahrener Computernutzer die Software nicht intuitiv begreift, besteht diesbezüglich noch erheblicher Verbesserungsbedarf. Warum kann das Versenden von verschlüsselten Mails nicht so einfach sein, wie bei bei "Telegram" zum Beispiel? Einfach auf "neuer geheimer Chat" klicken, und los geht's...

Inzwischen habe ich das Add-On deinstalliert, doch IMMER NOCH verlangt Thunderbird die Passworteingabe. Enigmail hat Thunderbird zerschossen!

PS: Inzwischen habe ich auch Thunderbird neu installiert, doch IMMER NOCH verlangt Thunderbird die Passworteingabe.

Superb! Rated 5 out of 5 stars

One of the best extensions out there for Thunderbird (the best email client around).

It's easy to setup, easy to use and, doesn't interfere at all with the way you already work... :)

PGP essential (HTML does work!) Rated 5 out of 5 stars

Although it admitedly has some quirks regarding the interface this extension works quite well. Does what its supposed to including HTML support (since PGP/MIME is enabled by default from 1.9 on)
Quote from the Enigmail 1.8 Manual (p. 49):
"HTML messages cannot be handled well, if you are using the OpenPGP inline format. The PGP/MIME format, however, can deal flawlessly with HTML messages. Unfortunately, not every mail client can interpret the PGP/MIME format."

Another plus: Thunderbird Conversations is compatible with Enigmail.

Completely messes up formatting settings Rated 1 out of 5 stars

A nice idea but it totally messes up all your HTML and wrap email formatting settings. Every email you send after installing is in plaintext mode, whether you use PGP or not. Plus there's a very ugly and intrusive toolbar. I'm a great fan of PGP but I uninstalled this add-on after less than a day because of the hassle. Then I had to spend ages resetting all the HTML composition settings for all my accounts and identities so Thunderbird would go back to how it was before (hint: make a backup of your profile before installing). I want to send maybe one or two encrypted emails every week. For those one or two, it's great. But the hassle for the other 99% just made it useless for me. If I need to use PGP I'll just encrypt my message using GnuPGP tools elsewhere and copy-and-paste it. Don't install this add-on unless you only ever want to send 1990s-style plaintext emails to everybody.

Rated 5 out of 5 stars

Ok,fantastico,funziona alla grande e decodifica rapidamente.Si integra perfettamente con le e-mail di Thunderbird.lunico problema se cosi lo vogliamo chiamare è stato creare la chiave pubblica,impiegando quasi 40 minuti,ma una volta realizzato non ci si pensa più.Faccio notare che HTML viene escluso in via di scrittura,ma si può ripristinare in seguito senza problemi dalle opzioni.Sapete io sono uno esigente e quindi senza le e-mail HTML non potrei vivere,comunque Enigmail invia testi solo in formato base,ma per quello che mi serve va bene,per non parlare dei File che si possono inviare anche codificati dallo stesso programma.Ve lo consiglio,lo uso su Linux.

Good but since version 1.8 the ugliest addon.... Rated 4 out of 5 stars

Great extension, been using it for year, but, seriously, who had the idea for that toolbar in the compose window? That's the ugliest thing I have ever seen. As an option for those with really poor eyesight okay but not as the only display for enigmail settings a no-go. That alone is worth removing one or two star.

Ich benutze Enigmail seit vielen Jahren. Es funktioniert einfach. Für die E-Mail-Sicherheit ist es unersetzlich.

Bugs werden immer sehr schnell behoben. Erst heute bin ich auf ein Problem mit der verschlüsselten Speicherung von Entwürfen in Version 1.8 gestoßen und habe in Bugzilla bereits den Vermerk gefunden, dass das Problem in 1.8.1 behoben ist. Jetzt muss die korrigierte Version nur noch in addons.mozilla.org auftauchen...

確実に動作します。私信の Security 対策に、必要不可欠な推奨品です。 Rated 5 out of 5 stars

遅ればせながらの Review です。
丁度、一年前から使用を始めました。
非常に有意義な機能で、気に入っています。

経験上、導入方法(install と set-up)と実際上の使い方(How-to)が平易ではない(It's Not Easy)と感じたため、簡単な解説を加えます。

①導入方法(install と set-up)と実際上の使い方(How-to)は、「ThunderbirdのHelp」→「プライバシーとセキュリティの設定」→「メッセージのデジタル署名と暗号化」で詳述されています。Tutorial(対話)形式で、解りやすくまとめられているのですが、解説量が多く、読み進めること自体の時間を要しますが。
②公開鍵「GnuPG」の入手が必要になります。数種のバージョンがありますが、Win版では「Gpg4win-Vanilla」(4MByte)で十分です。full version (30MByte)/-Light版(13MByte)は、「Enigmail」では使用することがない(パワーユーザー用途の)高機能版です。
③「Enigmail」の install を実行すると「設定ウィザード」が起動するので、各種の設定は簡単です。
④(Enigmail の)default は、英語/独語です。(解説は省きますが)多言語化は可能です。
⑤「秘密鍵」の作成と管理は、Kee-Pass(KeeFox)などの「パスワードマネージャー」の活用を推奨します。「Enigmail」でのパスワード認証は、自動ログイン機能もコピペ(Copy & Paste)も受け付けないので、作成時には(手入力に不自由しない文字種の選択などに)注意が必要です。
⑥「Enigmail」を使用すると送信用のメッセージは、「プレーンテキスト」形式に限定されるので、絵文字や修飾表示機能、文字種・サイズ変更などの使用が制限されます。
※HTML形式でメッセージを作成した場合は、送信時に plain-text(ASCII)への変換が成されますが、一部に文字化けが生じます。
⑦不測時における「失効」処理が可能です。⑧「公開鍵」なので、鍵の完全消失(Lost)のリスクもありません。

導入時と使用時に多少の難解さを感じたり、(プレーンテキスト形式に)面白味を欠いたりするとも思われますが、システムの完成度(安全で確実な暗号/複合化、高速通信化)を優先させた結果として、理解できます。

確実に動作します。私信の Security 対策に、必要不可欠な推奨品です。

Very nice! GPGMail is commercial now and i really dont trust in non-free software for encryption, so switched to thunderbird with enigmail ... awesome because it is fast (and imho fasterer than Mail.app), encryption and signing works and is highly visible, configuration is not that hard, just read trough the settings and skip what you dont get and change it later. Awesome and very important addon for privacy and freedom of the common man!

Funktioniert Rated 4 out of 5 stars

Wenn man sich einmal mit den Einstellungen zurecht gefunden hat, funktioniert Enigmail reibungslos. Das ständige Eingeben des Zugangsschlüssels, ist zwar etwas nervig aber dafür sicherer. Zum Entschlüsseln benötigt man auch immer Enigmail und man kann nicht schnell im Browser die Mails checken, aber das kann man Enigmail ja nicht anlasten ;)
