You have given a URL for the add-on, or the add-on you want is not on the “official” page. Searched for it, as shown above, does not detect your add-on.

Go to the web page in your browser, right-click the download link with your mouse, select “Save Link in this way”, and save the XPi file to your computer that you can find again. Download is temporarily recommended that you either use your downloads folder or your desktop.

To install a downloaded XPI file into Thunderbird you have two options.


Right-click the link and select Save or Save as shown previously.

You will be invited to download and save the file. Most browsers have a default download location, often on your desktop. Say where he downloads, and what is it called. Some add-on files contain silly names like “latest -234.xpi” which is not very useful when trying to find it later

You will need to navigate in the file picker to where you saved the XPI file and select it to complete the install.


  • Open the add-ons manager ( then )
  • Drag your downloaded XPI file to the add-on manager tab and drop it.

If you are using Windows, you can even skip the desktop bit. Open your browser and Thunderbird side by side, with Thunderbird’s Add-ons tab displayed. Drag the link directly from the browser onto Thunderbird’s Add-on tab. The main advantage of this method is that you don’t need to actually save a copy of the add-on on your hard disk before it is installed.
