'''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.
+
[https://www.thunderbird.net/en-US/ Thunderbird] is an open source email, news, and chat client previously developed by the Mozilla Foundation.
  
==Installation==
+
== Installation ==
To install, simply run:
 
# pacman -S thunderbird
 
  
This will install the unbranded (often called plain vanilla) Lanikai client.  It can be converted to the Mozilla branding (icons, etc) by installing the [http://aur.archlinux.org/packages.php?ID=34560 thunderbrand] script and running it as root:
+
[[Install]] the {{Pkg|thunderbird}} package, with a [https://www.archlinux.org/packages/?q=thunderbird-i18n language pack] if required.
# thunderbrand
 
More info is available in this [https://bbs.archlinux.org/viewtopic.php?id=49314 thread].
 
  
Another option is to install the mail client [http://aur.archlinux.org/packages.php?ID=10598 thunderbird-branded] from the AUR. It comes with the complete Mozilla packaging already in place.
+
Other versions include:

===Encryption with EnigMail===
+
A version overview, both past and future, can be read on [[MozillaWiki:Releases]].
  
====Installation====
+
== Securing ==
  
=====Via addons.mozilla.org=====
+
* Thunderbird sends your system's internal IP address to the configured SMTP server as an argument to the HELO/ELHO SMTP command. This value can be overridden by setting {{ic|mail.smtpserver.default.hello_argument}} to, for example, {{ic|localhost}}. Setting this value may increase the spam score of messages you send. See [http://kb.mozillazine.org/Replace_IP_address_with_name_in_headers] and [http://kb.mozillazine.org/Mail_and_news_settings].
  
{{Note|This method won't work for x86_64, see [[#Via AUR]].}}
+
* To hide Thunderbird's [https://developer.mozilla.org/en-US/docs/Web/HTTP/Gecko_user_agent_string_reference#Linux User Agent], create a new empty {{ic|general.useragent.override}} string entry in the [[#Config Editor]].
  
The first step to setting up email encryption is to download the GNU Privacy Guard (GnuPG). Several packages are needed for this:
+
* Thunderbird disables email images by default but enables HTML rendering which may expose IP address and location. To disable this click ''View > Message Body As > Plain Text''.
# 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.
+
* JavaScript is disabled for message content but not for RSS news feeds. To disable set {{ic|javascript.enabled}} to {{ic|false}} in the [[#Config Editor]].
  
=====Via enigmail.mozdev.org=====
+
== Extensions ==
  
EnigMail addons that works for x86_64 can be downloaded from [http://enigmail.mozdev.org/download/download-static.php.html this] page. Select the Arch build of the addon and follow the instructions in the previous section to install.
+

=====Via AUR=====
+
== Tips and tricks ==
  
There is an [[AUR]] package: {{Package AUR|enigmail}}.
+
=== Config Editor ===
  
=====Issues with the x86_64 version of enigmail=====
+
Thunderbird can be extensively configured by clicking ''Edit > Preferences > Advanced > General > Config Editor''.
  
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.
+
=== Set the default browser ===
  
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.
+
{{Note|Since version 24 the {{ic|network.protocol-handler.app.*}} keys have no effect and will not be able to set the default browser.}}
  
Open a new file called thunderbird.
+
Thunderbird uses the default browser as defined by the [[XDG MIME Applications]]. This is commonly modified by [[desktop environment]]s (for example [[GNOME]]'s Control Center: ''Details > Default Applications > Web'').
  
# nano /usr/bin/thunderbird
+
This can be overridden with {{ic|network.protocol-handler.warn-external}} in the [[#Config Editor]]
  
Write in the file:
+
If the following is all set to {{ic|false}} (default), set them to {{ic|true}} and Thunderbird will ask you which application to use when you click on a link (remember to also check ''"Remember my choice for .. links"'').
  
  /opt/thunderbird/thunderbird
+
  network.protocol-handler.warn-external.ftp
 +
network.protocol-handler.warn-external.http
 +
network.protocol-handler.warn-external.https
  
Finish with setting the right permissions and "updating" your shell.
+
=== Plain Text mode and font uniformity ===
  
# chmod 755 /usr/bin/thunderbird
+
Plain Text mode lets you view all your emails without HTML rendering and is available in ''View > Message Body As''. This defaults to the [[Wikipedia:Monospace_(Unicode)|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: {{Pkg|ttf-ubuntu-font-family}}).
# bash
 
  
====Creating a Keypair====
+
Remember to run {{ic|fc-cache -fv}} to update system font cache. See [[Font configuration]] for more information.
  
A keypair can be created by opening Thunderbird and finding the 'OpenPGP' menu and clicking 'Setup Wizard'. The wizard will now help you create your keypair. All of the options are fairly self-explanatory and are not discussed in this article.
+

 +
  </match>
 +
</fontconfig>
 +
</nowiki>}}
  
====Sharing your Public Key====
+
=== Webmail with Thunderbird ===
  
There are a variety of ways to distribute your 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.
+
:''See upstream Wiki: [http://kb.mozillazine.org/Using_webmail_with_your_email_client Using webmail with your email client].''
  
====Encrypting your Emails====
+
=== Migrate profile to another system ===
  
First of all, encryption does not always work properly with emails containing HTML. It is best to make all of the encrypted emails you wish to send plaintext. This can be ensured by going to Options in the 'New Email' window and finding Format, then clicking on "Plain-text only".
+
{{Tip|The [https://addons.mozilla.org/thunderbird/addon/importexporttools ImportExportTools] addon offers an option to export and import a profile folder.}}
  
Once you have chosen a recipient and title and have written your message, you can sign and encrypt the message by using the OpenPGP menu. Once that is done, simply click "Send" and your encrypted email has been sent.
+
Before you start with Importing or Exporting tasks, backup your complete {{ic|~/.thunderbird}} profile:
  
====Decrypting Emails====
+
$ cp -R ~/.thunderbird /to/backup/folder/
  
This article will not go into the details of key signing.
+
With migration you just copy your current Thunderbird profile to another PC or a new Thunderbird installation:
  
Assuming that the email was encrypted properly, just trying to open it should result in a popup window asking you to type in your keyphrase. Do so now, and the email will be decrypted for your viewing pleasure.
+
1. Install Thunderbird on the target PC
  
===Adding a Calendar with Lightning===
+
2. Start Thunderbird without doing anything and quit it.
  
Lightning is an extension that brings Sunbird's functionality to Thunderbird. This integrates calendar functions into Thunderbird.
+
3. Go to your Backup folder of your old Thunderbird installation
  
===Adding a Webmail Account with WebMail===
+
4. Enter the backup profile folder:
  
This issue is covered in the article [[Webmail with Thunderbird]].
+
$ cd /to/backup/folder/.thunderbird/<oldrandomnumber>.default/
 +
 
 +
5. Copy its content into the target profile folder {{ic|~/.thunderbird/<newrandomnumber>.default/}}
 +
 
 +
$ cp -R /to/backup/folder/.thunderbird/<oldrandomnumber>.default/* ~/.thunderbird/<newrandomnumber>.default/
 +
 
 +
=== Export and Import ===
 +
 
 +
Before you start with Importing or Exporting tasks, backup your complete {{ic|~/.thunderbird}} profile:
 +
 
 +
$ cp -R ~/.thunderbird /to/backup/folder/
 +
 
 +
If your accounts are broken or you want to join two different Thunderbird installations, you better install one Import and Export AddOn (eg. [https://addons.mozilla.org/thunderbird/addon/importexporttools ImportExportTools AddOn]) to both Thunderbird installations and following this just export and import all your data to the new installation.
 +
 
 +
=== Change the default sorting order ===
 +
Thunderbird (up to at least 31.4.0-1) sorts mail by date with the oldest on top without any threading. While this can be changed per folder, it is easier to set a sane default instead as described [https://superuser.com/questions/13518/change-the-default-sorting-order-in-thunderbird here].
 +
 
 +
Set these preferences in the [[#Config Editor]]:
 +
 
 +
mailnews.default_sort_order = 2 (descending)
 +
mailnews.default_view_flags = 1 (Threaded view)
 +
 
 +
=== Maildir support ===
 +
The default message store format is mbox. To enable the use of Maildir, see [[MozillaWiki:Thunderbird/Maildir]]. You basically have to set the following preference in the [[#Config Editor]]:
 +
 
 +
mail.serverDefaultStoreContractID = @mozilla.org/msgstore/maildirstore;1
 +
 
 +
Some limitations up to at least 31.4.0-1: only the "tmp" and "cur" directories are supported. The "new" directory is completely ignored. The read state of mails are stored in a separate ".msf" file, so initially all local mail using Maildir will be marked as unread even when located in the "cur" directory.
 +
 
 +
=== Spell checking ===
 +
 
 +
Install {{Pkg|hunspell}} and a [https://www.archlinux.org/packages/?q=hunspell+dict hunspell language dictionary] and restart Thunderbird.
 +
 
 +
See the Firefox article for [[Firefox#Firefox does not remember default spell check language|how to set the default spell checking language]].
 +
 
 +
=== Native notifications ===
 +
 
 +
Enable {{ic|mail.biff.use_system_alert}} in the [[#Config Editor]]. This option means that extensions (such as Gnome Integration) are not needed for these newer versions of Thunderbird.
 +
 
 +
=== Theming tweaks ===
 +
 
 +
Thunderbird should conform to [[GTK#Themes]] as defined on your system.  However, two tweaks are desirable for full consistency.  These are most beneficial for dark themes.
 +
 
 +
# To view the body of emails with colors following your theme:
 +
## Go to ''Preferences''
 +
## Select the ''Display'' tab
 +
## Click the ''Colors'' button
 +
## Check ''Use system colors''
 +
## Set the option for ''Override the colors specified by the content with my selection above'' to ''Always'' or ''Only with High Contrast themes''
 +
# To view Lightning calendar with colors following your theme:
 +
## Go to ''Preferences''
 +
## Select the ''Calendar'' tab
 +
## Check ''Optimize colors for accessibility''
 +
 
 +
Further customization can be attained by creating and editing a {{ic|userchrome.css}}.  See [[Firefox/Tweaks#General user interface CSS settings]] and [http://kb.mozillazine.org/UserChrome.css Mozillazine's userchrome page].

 +
 
 +
=== Error: Incoming server already exists ===
 +
 
 +
It seems Thunderbird (v24) still has that bug which pops up with "Incoming server already exists" if you want to reinstall a previously deleted account with the same account data afterwards. Unfortunately, if you get this error you can now only clean reinstall Thunderbird:
 +
 
 +
1. Make a backup of your current profile:
 +
 
 +
$ cp -R ~/.thunderbird /to/backup/folder/
 +
 
 +
2. Export all you Accounts, Calendar and Feeds via an AddOn like it's written in ''Export section'' of this Wiki.
 +
3. Uninstall your current Thunderbird installation
 +
 
 +
$ pacman -R thunderbird
 +
 
 +
4. Remove all your data by deleting your current Thunderbird folder {{ic|rm -R ~/.thunderbird/}}.
 +
 
 +
5. Install Thunderbird again:
 +
 
 +
$ pacman -S thunderbird
 +
 
 +
6. Create your mail accounts, feeds and calendars (empty).
 +
 
 +

 +
 
 +
8. Import all your data.

 +
=== Thunderbird UI freezes when receiving a new message ===
 +
 
 +
If Thunderbird is configured to show an alert when a new message arrives, or at launch, the lack of a notification daemon may freeze the interface (white screen) for many seconds. You can solve this issue by disabling alerts or installing a [[Desktop_notifications#Notification_servers|notification server]].
 +
 
 +
=== LC_TIME environment variable not respected ===
 +

Thunderbird should use the {{ic|LC_TIME}} environment variable for localization, but it might not do so in all contexts. Some problems can be mitigated by setting ''Edit'' > ''Preferences'' > ''Advanced'' > ''Date and Time Formatting'' to ''Regional settings locale'', a setting which was introduced in Thunderbird 56. However, there is a [https://bugzilla.mozilla.org/show_bug.cgi?id=1426907 bug report] for this issue.

Tips and tricks

Config Editor

Thunderbird can be extensively configured by clicking Edit > Preferences > Advanced > General > Config Editor.

Set 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.

Thunderbird uses the default browser as defined by the XDG MIME Applications. This is commonly modified by desktop environments (for example GNOME's Control Center: Details > Default Applications > Web).

This can be overridden with network.protocol-handler.warn-external in the #Config Editor

If the following is all set to false (default), set them to true and Thunderbird will ask you which application to use when you click on a link (remember to also 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>

Webmail with Thunderbird

See upstream Wiki: Using webmail with your email client.

Migrate profile to another system

Tip: The ImportExportTools addon offers an option to export and import a profile folder.

Before you start with Importing or Exporting tasks, backup your complete ~/.thunderbird profile:

$ cp -R ~/.thunderbird /to/backup/folder/

With migration you just copy your current Thunderbird profile to another PC or a new Thunderbird installation:

1. Install Thunderbird on the target PC

2. Start Thunderbird without doing anything and quit it.

3. Go to your Backup folder of your old Thunderbird installation

4. Enter the backup profile folder:

$ cd /to/backup/folder/.thunderbird/<oldrandomnumber>.default/

5. Copy its content into the target profile folder ~/.thunderbird/<newrandomnumber>.default/

$ cp -R /to/backup/folder/.thunderbird/<oldrandomnumber>.default/* ~/.thunderbird/<newrandomnumber>.default/

Export and Import

Before you start with Importing or Exporting tasks, backup your complete ~/.thunderbird profile:

$ cp -R ~/.thunderbird /to/backup/folder/

If your accounts are broken or you want to join two different Thunderbird installations, you better install one Import and Export AddOn (eg. ImportExportTools AddOn) to both Thunderbird installations and following this just export and import all your data to the new installation.

Change the default sorting order

Thunderbird (up to at least 31.4.0-1) sorts mail by date with the oldest on top without any threading. While this can be changed per folder, it is easier to set a sane default instead as described here.

Set these preferences in the #Config Editor:

mailnews.default_sort_order = 2 (descending)
mailnews.default_view_flags = 1 (Threaded view)

Maildir support

The default message store format is mbox. To enable the use of Maildir, see MozillaWiki:Thunderbird/Maildir. You basically have to set the following preference in the #Config Editor:

mail.serverDefaultStoreContractID = @mozilla.org/msgstore/maildirstore;1

Some limitations up to at least 31.4.0-1: only the "tmp" and "cur" directories are supported. The "new" directory is completely ignored. The read state of mails are stored in a separate ".msf" file, so initially all local mail using Maildir will be marked as unread even when located in the "cur" directory.

Spell checking

Install hunspell and a hunspell language dictionary and restart Thunderbird.

See the Firefox article for how to set the default spell checking language.

Native notifications

Enable mail.biff.use_system_alert in the #Config Editor. This option means that extensions (such as Gnome Integration) are not needed for these newer versions of Thunderbird.

Theming tweaks

Thunderbird should conform to GTK#Themes as defined on your system. However, two tweaks are desirable for full consistency. These are most beneficial for dark themes.

  1. To view the body of emails with colors following your theme:
    1. Go to Preferences
    2. Select the Display tab
    3. Click the Colors button
    4. Check Use system colors
    5. Set the option for Override the colors specified by the content with my selection above to Always or Only with High Contrast themes
  2. To view Lightning calendar with colors following your theme:
    1. Go to Preferences
    2. Select the Calendar tab
    3. Check Optimize colors for accessibility

Further customization can be attained by creating and editing a userchrome.css. See Firefox/Tweaks#General user interface CSS settings and Mozillazine's userchrome page.

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.

Error: Incoming server already exists

It seems Thunderbird (v24) still has that bug which pops up with "Incoming server already exists" if you want to reinstall a previously deleted account with the same account data afterwards. Unfortunately, if you get this error you can now only clean reinstall Thunderbird:

1. Make a backup of your current profile:

$ cp -R ~/.thunderbird /to/backup/folder/

2. Export all you Accounts, Calendar and Feeds via an AddOn like it's written in Export section of this Wiki. 3. Uninstall your current Thunderbird installation

$ pacman -R thunderbird

4. Remove all your data by deleting your current Thunderbird folder rm -R ~/.thunderbird/.

5. Install Thunderbird again:

$ pacman -S thunderbird

6. Create your mail accounts, feeds and calendars (empty).

7. Install the ImportExportTools AddOn

8. Import all your data.

Thunderbird UI freezes when receiving a new message

If Thunderbird is configured to show an alert when a new message arrives, or at launch, the lack of a notification daemon may freeze the interface (white screen) for many seconds. You can solve this issue by disabling alerts or installing a notification server.

LC_TIME environment variable not respected

Thunderbird should use the LC_TIME environment variable for localization, but it might not do so in all contexts. Some problems can be mitigated by setting Edit > Preferences > Advanced > Date and Time Formatting to Regional settings locale, a setting which was introduced in Thunderbird 56. However, there is a bug report for this issue.
