addressContext is an extension designed to speed up the process of adding email addresses to the address book in Mozilla Thunderbird. addressContext adds an entry to the context menu that allows you to choose between:

• Add Senders/Recipients as Cards -Adds the senders or recipients of all selected messages to the address book, presenting a dialogue window for each sender to allow customization.
• Add Senders/Recipients as List -Adds the senders or recipients of all selected messages to the address book to a new Mailing List entry. Further, since mailing list entries are really Address Book subdirectories, will add the recipients to the main address book, as well.

Install addressContext for Seamonkey:
addresscontext-0.8-mod.xpi
addresscontext-0.7-mod.xpi

Just select the messages containing the attachments you want to extract and select 'Extract Attachments' and this extension does the rest. No more having to go through each message to extract the attachments!

xSidebar needs to be installed for the options dialog to work.

Install Attachment Extractor for Seamonkey:
attachmentextractor0.9.1.1-mod.xpi
This extension is only for SeaMonkey 1.1. It will not work properly in 1.0, 1.5a, nor in SuiteRunner

Attachment Sizes adds the ability to see attachment sizes:

1. in the attachment box on messages.
2. in the attachment box on composes.

Install Attachment Sizes for Seamonkey:
attachment_sizes-0.0.8.xpi
attachment_sizes-0.0.5-mod.xpi

To configure ConfigDate in SeaMonkey, select Edit —> Preferences... —> Mail & Newsgroups —> Date configuration

Note:

• The 5 date formats are given by Thunderbird itself.
• The date formats are depending on your systems/regions setting, too (e.g.: "25.08.2005 15:54" in Germany or "2005/08/25 15:54" in US).

Visit extensions homepage for more information including instructions to get the ISO date format, install instructions and a locales list: http://configdate.thunderbird-mail.de/index-en.php

Install ConfigDate for Seamonkey:
configdate-0.5-mod.xpi (Updated for SuiteRunner)
configdate-0.4.1-mod.xpi
configdate-0.3.8-mod.xpi

Mod-Notes:

Version 0.8.2-mod: Updated the Thunderbird component to 1.1.3. Fixed a logic error that was causing errors in the Error Console.

Version 0.8.1-mod: Fixes breakage on SuiteRunner builds due to switching to the hunspell engine. I've also improved compatibility with SeaMonkey 1.0 builds.

Install Dictionary Switcher for Seamonkey:
dictionary_switcher-0.9-mod.xpi
dictionary_switcher-0.8.2-mod.xpi
dictionary_switcher-0.8.1-mod.xpi
dictionary_switcher-0.8-mod.xpi
dictionary_switcher-0.8-mod.xpi

Currently only one address book can be searched at a time. Users with multiple address books cannot search for duplicates between address books. This feature is planned for a future version.

Install Duplicate Contact Manager for Seamonkey:
duplicate_contact_manager-0.6-mod.xpi (SeaMonkey 1.0/1.1.* only).

Changes in this version: The Mailto option will open the integrated Mail client in SeaMonkey directly; and in Firefox it will invoke the internal Firefox API that opens an external mail client directly instead of the cumbersome and roundabout method currently used.

Install Email This! for Seamonkey:
email_this_bookmarklet_extension-2.0.0-fx.xpi (SuiteRunner Ready requires xSidebar).

The second thing this extension does is allow you to set a default To address for newly composed messages based on which folder you are working in. This could be very useful for mailing lists – when you create a new message in the mailing list folder, your message would automatically be correctly addressed.

In both cases, if the current folder has no From address or To address specified, the extension will check the parent folder, so you can control the settings for an entire branch of your folder tree at one time.

Install Folder Account for Seamonkey:
folder_account-0.84-mod.xpi SuiteRunner Ready
folder_account-0.78-mod.xpi SuiteRunner Ready
folder_account-0.72-tb.xpi

You can set arbitrary flags on arbitrary folders, too. Mostly I think this makes the icons change, except the 'Junk' flag, which accomplishes what I described above. Right click on a folder in the main view and find 'Flags...' (if you're using the U.S. English version) to change flags on a certain folder.

Install Folder Flags for Seamonkey:
folderflags-1.0-mod.xpi

Folderpane Tools allows for customization of the Thunderbird folder pane. Accounts can be rearranged and the startup folder can be chosen. For more information about using the extension, visit the extension homepage. Requires Thunderbird 1.0-2.0.

Install Folderpane Tools for Seamonkey:
folderpane_tools-0.0.5-tb.xpi

Thunderbird, like many other email clients, uses the mbox format to archive email. It's curious that Thunderbird does not have a function that lets you import or export files in this format and this lack is sometimes a problem when you want to move the accounts from a pc to another one or when you want to migrate (for example) from Mozilla to Thunderbird.

MboxImport makes the import/export of mbox files very easy.

To import, you must select the destination folder, then right-click and choose the item "Import mbox file" from the menu "Import/export". To export, simply right-click on the folder or on the account and to choose the item you want from the menu "Import/export". The menu is also under "Tools".

ImportExportTools (MboxImport enhanced) now allows you to export and import messages with more flexibility, with the following options:

• Tools Menu --> Import/Export in mbox/eml format
• Context menu on folders panel --> Import/Export in mbox/eml format
  • export of folder in a single file (mbox format), with also the subfolders if you want;
  • export of all messages in single files (eml format);
  • export of all messages in single files (html or plain text format), with an index;
  • export of all messages in one single plain text file;
  • export of the index of the messages in a folder;
  • mbox files import;
  • eml files import;
  • import of all the eml files existing in a directory;
• File menu --> Save selected messages
• Context menu of thread panel --> Save selected messages
  • saving multiple messages in eml/html/plain text format with just a click;
• Edit menu --> Copy message to clipboard
• Context menu of thread panel --> Copy message to clipboard
  • copy the message with headers to clipboard.
• Context menu on an EML attachment
  • import file in the folder

Install ImportExportTools for Seamonkey:
ImportExportTools-1.7.1-mod.xpi
ImportExportTools-1.6.1-mod.xpi

LookOut is a plugin which allows will allow Thunderbird to interface with Microsoft's mail tools by decoding metadata and attachments encapsulated/embedded in a TNEF encoded attachment. The TNEF decoding engine was inspired (with permission) by the tnef.sf.net project.

There are a few tnef decoders out there that do an excellent job. One could simply use one of these decoders as a helper application. This extension was created for two reasons. The first being that LookOut allows you to see what files are hidden in the anonymous encapsulation (winmail.dat). The second reason is the realization that some lack the desire to opperate more than one or two nonintegrated applications and LookOut makes the decoding part of the application. I would throw up a screenshot but that would be useless as LookOut is designed to be in the shadows doing it's thing and not be seen.

It should be noted that TNEF encapsulations will put a higher net and proc load on the IMAP server (or any other server for that matter). This is because there is no way for the client to ask for a sub-part of the TNEF file (whereas it can ask for a MIME part). If the client is to extract any sub-parts of the TNEF part it will need them all.

Install LookOut for Seamonkey:
lookout-1.2.1-mod.xpi (For SeaMonkey 1.0 and 1.1.* only. This version doesn't work in SuiteRunner)
lookout-1.2-mod.xpi (2007072301) (For SeaMonkey 1.0 and 1.1.* only. This version doesn't work in SuiteRunner)
lookout-2007011003-mod.xpi

MessageFaces lets Mozilla Thunderbird display 'face' images in the message header section of e-mails and newsgroup messages. These face images are intended to represent the sender, in the form of photos, cartoons, logos and so on. MessageFaces supports the following Face types:

Install MessageFaces for Seamonkey:
messagefaces_1_1.xpi

No New Window on Double Click prevents Thunderbird from opening a new main window. When you double click on a folder in the folder pane, the folder will expand or collapse if it has subfolders. Also, when a program tries to run Thunderbird while it is already running, the new window is closed and the first main window will be brought to focus. New mail windows can still be opened when right-clicking on a folder and selecting Open in New Mail Window. This mod works in SeaMonkey 1.0 to 2.0a and should work in Thunderbird 1.5 to 3.0a.

In SeaMonkey 1.1 and above, you can go to about:config and change the setting mailnews.reuse_thread_window2 to true to achieve the same effect. In this case the only additional functionality that NNWODC provides is to close additional Messenger windows invoked by external applications.

Install No New Window on Double Click for Seamonkey:
nnwodc-0.2.3.xpi

Nostalgy adds keyboard shortcuts to change folder, move/copy messages, with folder name auto-completion (using only the keyboard). Same for tags. Also includes a system of rules to suggest a target folder for saving messages; re-creates Eudora's Alt-Click; facilitates navigation in the 3-pane window; makes it easy to change between To/Bcc/Cc fields in the composer; facilitates tag-oriented operations. All that with the keyboard only!

Other keyboard actions include: changing focus between panes, scroll the message while keeping the focus on the thread pane, changing header in the composer (To/Cc/Bcc), adding an attachment, hide the folder view. Save time and get back the productivity you were used to with mutt/pine/eudora!

Install Nostalgy for Seamonkey:
nostalgy-0.2.15-mod.xpi

This version has been modified for SuiteRunner. I've basically merged the Suite and Thunderbird versions (the differences were trivial) so this version will work across Thunderbird, XPFE/SeaMonkey and the new SuiteRunner.

Install Quote Colors for Seamonkey:
quotecolors-0.2.8-mod.xpi

Remote Image Cache was done as a request for someone on the Mozillazine forums. It's in the sandbox at AMO so you'll have to be a registered user to view it there. Here is the text from the AMO page explaining how it works:

Saves remote images from emails locally when mail is viewed for the first time. This allows you to view mails with remote images and have them display correctly even if you’re offline or the server hosting the remote images is down. The extension fully supports the remote content blocking policy of the user and won't get the images until the user has allowed it for the given message. Some Q and A

Install Remote Image Cache for Seamonkey:
remote_image_cache-1.0-mod.xpi

Enable the message filters automatically on the sent folder. It adds a checkbox to the filter setting dialog and allows you enable the filters autorun on the folder which you save your sent messages at after sending.

NOTE: This add-on runs as the same as you select from menu tool->Run Filters on Folder, just autorun after sending. So you should be careful of your filter define, perhaps you just defined your filter against to the incoming messages, but TB can not differentiate which is for incoming and which is for outgoing. So when they are be run at the sent folder, you maybe get a strange result. A way to avoid this is that add a "from" condition to the filters which you want they are be run on sending, and also add a "to" condition to the filters which are for incoming. Of course, the value is your own mail address.

Install Send Filter for Seamonkey:
send_filter-0.9-mod.xpi

Signature inserts custom text into forum posts and emails (i.e. attach a signature to your emails).

TagZilla is an add-on to Mozilla that lets you add a tagline, random or specifically chosen by you, to the end of an email or newsgroup posting, or to the clipboard for pasting into a Web-based email or message board.

What is a tagline?

A tagline is a one-line joke, witticism, factoid, what have you. It can be about any subject (although it's good to ensure it's appropriate to the forum in question). The random quotes that can be found at the end of web pages like Slashdot or the MozDev home page could be considered taglines.

Install Tagzilla 0.066.1 for Seamonkey and SuiteRunner. Contains the latest patches not in the official versions yet.
tagzilla-0.066.1.xpi

• [Updated] SuiteRunner Ready.
• [Fixed] Missing strings in the de-DE and de-AT locales.
• [Fixed] Access settings for all identities in each account and not just the default identity.

All patches have been rolled into the latest official Tagzilla Releases which can be obtained from http://tagzilla.mozdev.org/ .

These are unofficial bug fix versions which I've made to Tagzilla 0.059 in order to get it working in current versions of SeaMonkey, Thunderbird, and Firefox. These changes will make their way eventually to the official Tagzilla releases.

• [New] es-AR locale.
• [New] Added tooltip to the toolbar buttons.
• [New] style="width:32em;" code to fix the options dialog in Thunderbird.
• [New] Resized toolbar icons ( small: 16x16 & large: 24x24 px).
• [Fixed] If you insert a tagline when composing an email, it won't ask you to insert another when you send.
• [Fixed] In auto mode, the tagzilla window opens after the mail is sent. Now it should open before the mail is sent allowing you to select a tagline.
• [Fixed] In manual mode an additional tagzilla window opens after the mail is sent.
• [Added] Russian Locale contributed by someone on the Tagzilla mailing list.
• [Fixed] Error in the Pref dialog unload handler.
• [Fixed] Rewritten the Preference dialog to use an overlay instead of an iframe. This should stop the bottom of the dialog getting cut off.
• [Changed] Increased the width of the tagline sample display textboxes (In the preference dialog) so that the scroll bar doesn't appear unnecessarily.
• [Changed] Bumped the maxVersion for Thunderbird and Firefox to 3.0.*.

The Unselect Message extension prevents Thunderbird from selecting the next message after you've deleted or moved the previously selected ones. Stay in control of which message you want to have selected and displayed in the preview pane; that piece of spam you're deleting really shouldn't have a say in that.

In addition, you can click into the empty space below the last message in the thread list to unselect the currently selected message and to clear the preview pane.

This extension works best with the "Remember the last selected message" option unchecked. If you have it checked, the last message Thunderbird remembers will indeed be the one which was selected before you unselected all of them.

Install Unselect Message for Seamonkey:
Unselect_Message_1.3-mod.xpi
