Below you can find a regularly updated list of Thunderbird extensions that are either essential or very useful when using the program.

Because the list is not very long, it is not divided into sections.

One advice for people eager to try new extensions - always check the extension's privacy policy. If it is longer that something like "We do not collect any user data.", be cautious. As a rule of thumb, try not to use any add-on that has a "Custom License" - install only the open source ones (Mozilla Public License, GNU GPL or MIT).

Because the list is periodically updated, if you want to stay up to date with the latest additions and deletions, you can use the Web Pages Scanner extension to be notified about any changes made here.

Extensions

uBlock Origin

Finally, an efficient wide-spectrum content blocker. Easy on CPU and memory.

uBlock Origin is not an "ad blocker", it's a wide-spectrum content blocker with CPU and memory efficiency as a primary feature.

Not available on Thunderbird addons page, you need to download it directly from authors Gitub page.

Markdown Here Revival

Markdown Here Revival lets you write email in Markdown and render it (make it pretty!) before sending.

Very easy to use:
1. Write your email in Markdown.
2. Click the Markdown Toggle button in the format toolbar.
3. It's pretty!

This is an open source project forked from Markdown Here to support modern Thunderbird versions.

CardBook

This add-on allows you to manage all your contacts under the vCard standard.

BorderColors D

If you have Thundebird configured with multiple accounts or identities, you might have sent emails from the wrong one once or twice. This add-on tries to prevent that mistake by adding a colorful border around the "New message" window. You can configure each identity to have a different color.

Lightning Calendar Tabs

Displays tabs which allows quick navigation between time periods in Lightning calendar. All views of calendar are supported. Color of tab texts can be adjusted.

Quicktext

Using Thunderbird, Quicktext is the perfect tool to help you quickly answer routine, repetitive emails. Quicktext performs both simple and complex tasks. The extension can insert different signatures into your emails depending on whom you are sending the email to.

Even better, you can use variables like [[TO=firstname]] to personalize your emails. You can also specify the subject and which attachments to add when creating a template for your email.

If you are a new user to Quicktext, start with reading the pages in the getting started section of the quicktext wiki. They will help you with installing and setting up Quicktext.

MessagePreview

MessagePreview adds a column to the Thunderbird message list to display the message preview in a tooltip on column row icon mouse hover or a short preview in the column row itself.

XNote++

XNote allows you to create a note for each mail. Thus, you can add for example the phone number of that contact or when you have to contact the sender back.

Features: - Add notes to messages - Custom column to mark messages with notes. - Highlight messages with notes. - Resizeable notes - Preset standard note position of screen, even outside of TB main window. - Create notes by keyboard only (no mouse needed). - Translated into Dutch, English, French, Galician, German, Italian, Japanese, and Polish.

Windows Taskbar Unread Badge

Put an unread mail count badge on the Thunderbird icon in the Windows taskbar.

ThirdStats

Beautifully visualized statistics for your Thunderbird Email Accounts.

Textmarker

Highlights selected text when composing emails. Default colour is yellow - other colours are available via Options.

Send Later

This add-on changes the "Send Later" command (Ctrl+Shift+Return) in the message composition window, so that instead of merely copying the message into your Outbox so that it is sent the next time you go online or do "Send Unsent Messages", a dialog pops up which allows you to specify when the message will be sent.

You can specify a specific time and date, or click "15 mins later", "30 mins later" or "2 hours later", or define custom shortcuts. You can also schedule a message to send repeatedly using simple rules (every N hours, days, etc.) or customizable functions.
