ThunderBird Add-ons I use for Getting Things Done.

October 13, 2008

First and foremost I think we should do our best not to send misspelled emails so install all the dictionaries you need from


Must have calendar for Thunderbird. If you’re looking to throw away Outlook you have to start here.


Automatically compress attachments before you send your messages. It is easily configured to ZIP all attachments to a single file, or multiple files, ignore certain files or not to zip them if gains are not noticeable. unfortunately AutoZip does not work for Mac users at this point.


LookOut allows Thunderbird to work with Microsoft’s mail tools by decoding metadata and attachments encapsulated/embedded in a TNEF encoded attachment (aka winmail.dat).

This is an unavoidable add-on since most of your Outlook friends will send RTF formated email with the dreaded winmail.dat attachment. To educate them, and make everybody’s life a little easier have them reconfigure their Outlook client to stop sending email in Rich Text Format (RFT). For more information on how to do stop sending Winmail.dat files visit Microsoft’s Knowledgebase

Simply you need to Turn off Rich Text for messages in Microsoft Outlook

  1. Click on Tools
  2. Click Options, and then click the Mail Format tab.
  3. In the Send in this Message Format list, select Plain Text or HTML, and then click OK.

Now everyone, no matter what email program they are using, will be able to receive your email with no problems.

Priority Switcher

Change priority of the received messages from the toolbar button and the context menus…

Makes life easier by allowing to quickly change message priority in the compose window.


Quicktext is an extension for Thunderbird that lets you create templates that can be easily inserted into your own emails.

This one is a big time-saver, since you can create many text snippets or whole email templates that expand on demand from keywords or key-strokes.


Seek adds faceted browsing features to Mozilla Thunderbird and lets you search through your email more effectively. Quick and easy search for those hard to find emails.

Tag ToolBar

Simple way to attache a tag to a message with one mouse click
