10 Must-Have Toolbar Buttons for Thunderbird 3

Streamline Thunderbird with Essential Toolbar Buttons
Do you find yourself spending excessive time navigating Thunderbird’s menus to complete routine actions? Are the keyboard shortcuts difficult to recall? Enhancing your workflow with visual shortcuts might be the solution.
Thunderbird toolbar buttons offer instant access to many of the application’s most valuable features. Furthermore, these buttons can introduce new functionalities that you might otherwise overlook.
Below are 10 must-have toolbar buttons for Thunderbird 3!
To integrate these buttons, right-click on your Thunderbird navigation bar or toolbar and select Customize.... This will open the Customize Toolbar window, where you can drag and drop buttons into your desired location and even Add New Toolbars.
1. Get All Mails [No Longer Available]

While Thunderbird 3 includes a Get Mail button, retrieving mail for all accounts typically requires two clicks.
If you consistently check all accounts simultaneously, this button streamlines the process by automatically fetching new mail from every configured account.
2. Remove Duplicate Messages (Alternate)

This extension enables you to efficiently search for and eliminate duplicate messages within your inbox.
By clicking the arrow in the lower right corner, you can define the criteria for comparison, including author, recipients, CC list, status flags, message ID, line count, send time, size, subject, folder, and message body. The extension then searches all folders within a selected email account.

3. Mark All Read

Occasionally, an unread message may remain in a folder, or you might receive numerous emails to review at a later time. This button allows you to quickly mark all messages as read, eliminating the need for individual selection.
4. Restart Thunderbird

Thunderbird 3 typically only offers a restart option after installing a new add-on. This button empowers you to initiate a restart whenever necessary, directly from your toolbar.
5. Exit Button

Closing Thunderbird properly requires navigating to File > Exit. While closing the window via the operating system is faster, it often fails to fully shut down the application, leaving it running in the background.
The Exit button provides direct access to the Exit function, saving you a click.
6. New Tab Button

Thunderbird 3 supports tabbed browsing. If you frequently utilize the built-in Thunderbird browser, the New Tab Button extension will prove highly beneficial.
Explore the extension’s options to customize its behavior, including the button’s placement.

7. Xpunge

The Thunderbird profile folder can become quite large, partly because deleted emails are not always permanently removed. To ensure complete deletion, you need to compact your folders.
Xpunge adds a toolbar button that allows you to empty the trash and compact folders across one or multiple accounts with a single click.

8. Filter Button

Filters are rules that automatically sort incoming mail into designated folders. This button enables you to execute your filters with a single click.

9. Toolbar Buttons
Avoid the hassle of downloading numerous extensions individually. This extension provides 50 buttons for Thunderbird, along with many more for Firefox and Sunbird. It offers a wealth of useful features and allows for extensive customization.

10. Custom Buttons²

Still lacking specific buttons? Custom Buttons² allows you to convert bookmarklets into buttons or build, maintain, import, and export custom toolbar buttons.
If you prefer not to create buttons yourself, this extension allows you to import pre-made buttons from the Custom Buttons² website.

Select a Thunderbird-compatible button, right-click the link to install it, copy the URL to your clipboard, and then return to Thunderbird and press the Insert a Button² button on your toolbar. The button will appear instantly.
