Add-Ons

Currently in use

Nostalgy

• Note: Auto-completion does not appear at first.

Copy Sent To Current

• Allows to (additionally) save a copy of sent messages to the current folder or choose folder on send
• Not working when used with MRC Compose.

Virtual Identity

MRC Compose

• Provides standards fields (TO, CC, BCC) with autocomplete to Thunderbird's compose pane. (See bugzilla 440377).

Tested or no longer used

Quick Folder Move

• Nostalgy is a better alternative

Enigmail - GPG support

Recommended settings for Enigmail

• Disable loading of IMAP parts on demand
• Disable flowed text (RFC 2646)
• View message body as plain text
• Use 8-bit encoding for message sending
• Do not compose HTML messages

Fix Message Integrity errors

This is due to last Enigmail policy to not decrypt anymore without MDC.

To get freedom back, rebuild Enigmail as follows [1]:

Clone the repository:

git clone https://gitlab.com/enigmail/enigmail/
git checkout enigmail-2.0.8

diff --git a/package/errorHandling.jsm b/package/errorHandling.jsm
index 15f561a..f87554e 100644

   }
 }

Rebuild:

./build.sh

In Thunderbird, uninstall previous add-on and install the new one from file.

Tips

Automatically sync all folders in Thunderbird

From here:

• open the Config Editor (Tools → Options → Advanced → General → Config Editor),
• change the mail.server.default.check_all_folders_for_new setting to true.

Filter incoming messages based on Bcc:

Say you have subscribed to mailing list, sending to XYZ@mail.com, and want to move these messages to a custom folder.

• Create a new filter
• In the header list, click Customize..., and create a custom header named Delivered-To.
• Use rule Delivered-To contains XYZ@mail.com.

Silent SoGo 'no changes' notification

This is very annoying. Everytime SoGo synchronizes, we get a pop up notification, most of the time saying "no changes" [2].

To silent:

• Open address book.
• Right click on SoGo account book, then 'properties'.
• Untick 'show notifications'.

Disable Ctrl-Enter / Send Now shortcut

By default, ctrl-enter in TB triggers Send Now action.

To disable this behaviour:

• Install Dorando Keyconfig add-on.
• Compose a new mail
• In the mail composition window, go to Tools → Keyconfig, then select Send Now shortcut and click on disable.

Troubleshoot

Sent folder not updated

Like a corruption of the TB database [3]. Go to ~/.thunderbird/*.default:

sqlite3 global-messages-db.sqlite vacuum

Mail not deleted

Deleting a mail seems a hard task in Thunderbird [4]:

• Set mail.imap.expunge_after_delete to true.

Missing mails, IMAP folder not synced

• Right click on IMAP folder, select Properties.
• In the General Information tab, click Repair Folder button.

Sync bugs

• bug 712595

About IDLE, and CONDSTORE flag/support.

Proxy not working

• Proxy does not work with IMAP. See bug 1263295 and bug 1230823.

• Refuse to connect to localhost in all possible ways.
• Only work-around is to keep the proxy disabled, and enabled it only when e.g. to sync Owncloud address book.

Broken text edition mode

• Relevant bugs bugzilla 216132, bugzilla 140800
• Relevant posts mozillazine
• My bug bug 1288914

Fix:

• In Preferences → Composition → General → HTML Font, select Variable Width. This way this makes apparent that edition is in HTML mode. Also, there will not be a weird font change when pasting text at the end of a reply.
• To force text-edition mode, use Shift-click on either Write, reply or forward.

IMAP folder list not updated

• Relevant questions on SO question 392320
• Thunderbird does a refresh on startup. One can force a refresh by collapsing / expanding the parent folder in folder tree view.

Cannot dismiss reminders

I keep getting reminder about a past birthday, although I dismissed it several times.

• Workaround — Uncheck "Show missed reminder" under Preferences > Calendar > Reminders [5].

Big emojis appearing in the message list

See this bug.

The fix was to install fonts-symbola:

sudo apt install fonts-symbola
