'''Mozilla Thunderbird''' is an email, newsgroup, and news feed client designed around simplicity and full-featuredness while avoiding bloat. Due to its modification with several patches, it is known on Arch Linux as '''Lanikai'''. It supports POP, IMAP, SMTP, S/MIME, and OpenPGP encryption (through the Enigmail extension). Similarly to Firefox, it has a wide variety of extension and addons available for download that add more features.

== Extensions ==
  
The first step to setting up email encryption is to download the GNU Privacy Guard (GnuPG). Several packages are needed for this:
+
=== EnigMail - Encryption ===
# pacman -S gnupg gnupg2 gpgme
+
  
EnigMail can be downloaded from [https://addons.mozilla.org/en-US/thunderbird/addon/71 here], at Mozilla's addon database. Make sure that it is installed as a Thunderbird addon and isn't automatically interpreted to be a Firefox addon. This can be done by going to Tools -> Add-ons and clicking Install, then selecting the XPI addon package. Congratulations, EnigMail is now installed. You should now restart Thunderbird.

==== Sharing the public key ====
  
=====Issues with the x86_64 version of enigmail=====
+
There are a variety of ways to distribute the public key. One way is to upload it to a public keyserver network. Another is to share it with friends who are also using email encryption.
  
It is possible that Thunderbird (Lanikai) hasn't got the same build-type (Error: Linux_x86-gcc3) as the enigmail (x86_64) and won't get installed. Downloading Thunderbird in the i686 version an installing enigmail by the Add-On application works fine.
+
==== Encrypting emails ====
  
If you download Thunderbird manually, remember copying the files to {{Filename|/opt}} and creating a directory for Thunderbird. To still be able start Thunderbird from the "default location" create a file that points at {{Filename|/opt/thunderbird/thunderbird}} for example.

First of all, encryption does not always work properly with emails containing HTML. It is best to make all of the encrypted emails plain text by choosing ''Options > Delivery Format > Plain Text Only'' in the new email window.

Once the email is finished it can be signed through the ''OpenPGP'' menu.
  
# nano /usr/bin/thunderbird

Mozilla Thunderbird is an email, newsgroup, and news feed client designed around simplicity and full-featuredness, while avoiding bloat. It supports POP, IMAP, SMTP, S/MIME, and OpenPGP encryption (through the Enigmail extension). Similarly to Firefox, it has a wide variety of extension and addons available for download that add more features.

Installation

Install thunderbird from the official repositories.

Other alternatives from the AUR include:

There are a number of language packs available, if English is not your preferred language. To see a list of available language packs, try:

$ pacman -Ss thunderbird-i18n

Extensions

EnigMail - Encryption

EnigMail is an extension that allows writing and receiving email signed and/or encrypted with the OpenPGP standard. It relies on the GNU Privacy Guard (GnuPG).

It can be installed from addons.mozilla.org (e.g. through the Add-ons Manager) or the AUR. Common packages are: thunderbird-enigmailAUR and thunderbird-enigmail-binAUR.

Sharing the public key

There are a variety of ways to distribute the public key. One way is to upload it to a public keyserver network. Another is to share it with friends who are also using email encryption.

Encrypting emails

First of all, encryption does not always work properly with emails containing HTML. It is best to make all of the encrypted emails plain text by choosing Options > Delivery Format > Plain Text Only in the new email window.

Once the email is finished it can be signed through the OpenPGP menu.

Decrypting emails

Assuming that the email was encrypted properly, just trying to open it should result in a popup window asking to type in the keyphrase.

Lightning - Calendar

Lightning is a calendar extension that brings Sunbird's functionality to Thunderbird. You can use addons.mozilla.org or the AUR package lightning-binAUR to install Lightning.

FireTray - Tray icon

FireTray is an extension that adds a customizable system tray icon for Thunderbird. It can be installed from addons.mozilla.org or the AUR package thunderbird-firetrayAUR.

Tips and tricks

Setting the default browser

Note: Since version 24 the network.protocol-handler.app.* keys have no effect and will not be able to set the default browser.

Recent versions of Thunderbird use the default browser as defined by the system MIME settings. This is commonly modified by the Gnome Control Center (Gnome Control Center > Details > Default Applications > Web) (available in: gnome-control-center).

This can be overridden in Thunderbird through Edit > Preferences > Advanced > General > Config Editor by searching for network.protocol-handler.warn-external.

If the following three are all set to false (default), turn them to true, and then Thunderbird will ask you when clicking on links which application to use. Depending on the chosen desktop, common values include /usr/bin/firefox, /usr/bin/google-chrome-stable, /usr/bin/exo-open (Xfce) or /usr/bin/xdg-open (non-DE environments). Remember to check "Remember my choice for .. links".

network.protocol-handler.warn-external.ftp
network.protocol-handler.warn-external.http
network.protocol-handler.warn-external.https

Plain Text mode and font uniformity

Plain Text mode lets you view all your emails without HTML rendering and is available in View > Message Body As. This defaults to the Monospace font but the size is still inherited from original system fontconfig settings. The following example will overwrite this with Ubuntu Mono of 10 pixels (available in: ttf-ubuntu-font-family).

Remember to run fc-cache -fv to update system font cache. See Font Configuration for more information.

~/.config/fontconfig/fonts.conf
<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<fontconfig>
  <match target="pattern">
    <test qual="any" name="family"><string>monospace</string></test>
    <edit name="family" mode="assign" binding="same"><string>Ubuntu Mono</string></edit>
    <!-- For Thunderbird, lowering default font size to 10 for uniformity -->
    <edit name="pixelsize" mode="assign"><int>10</int></edit>
  </match>
</fontconfig>

Troubleshooting

LDAP Segfault

An LDAP clash (Bugzilla#292127) arises on systems configured to use it to fetch user information. A possible workaround consists of renaming the conflicting bundled LDAP library.
