    Thunderbird-Version: 17.0.8
    Betriebssystem + Version: Mac OS X 10.9
    Kontenart (POP / IMAP): IMAP
    Postfachanbieter (z.B. GMX): 1&1

    Wie im Titel schon angegeben, gibt es eine Möglichkeit, sich eine Art Firefox-Sync für Thunderbird aus Add-ons zu bauen? (evtl. über Cloud-Speicher wie Dropbox & Co.)?

Add-ons are little apps that add new functionality to Thunderbird (extensions) or change its appearance (themes). This article shows you how to install an add-on to your Thunderbird.

  • 2A slightly less ideal case (Install from a downloaded XPI file)

In an ideal world, all the add-ons you would want are officially vetted, approved, and can be found on the official website,

For add-ons that fall into this category, you can simply go to the Add-ons Manager tab in Thunderbird by clicking the menu button followed by Add-ons and click on the Extensions panel on the left to display the search box in the top-right corner. Enter the add-on's name or enough of it to limit the search results returned to a manageable number and press EnterReturn or click the magnifying glass icon.

Once you have done your first search, a new Search category appears in the panel on the left. You can keep refining your search until you find what you want.

How to install thunderbird addon

Here is a search for add-ons that mention 'Contacts':


Once you locate an add-on you like, click on , wait for it to be downloaded, then click on Restart now if prompted.

You may have been given an URL for the add-on, or the add-on you want isn't on the 'official' page. Searching for it, as shown above, doesn't locate the add-on.

Visit the webpage in your browser, right-click the download link with your mouse, select Save Link As… and save the XPI file to a location on your computer that is easy to remember. As the download is temporary, it is suggested you use either your Downloads folder or your desktop.

If you are using older versions of Firefox, a left-click on the download link will cause the browser to try and install the add-on into Firefox itself. This invariably results in an error about compatibility, as the add-on is designed for Thunderbird. If you're using another browser, a left-click might result in your browser attempting to download and 'open' the XPI file. This is basically a small program, so it is not meant to be opened. It has to be saved to disk.

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


Right-click the link and select Save As… or Save Link As… as described earlier.

You will be invited to download and save the file. Most browsers have a default download location. Make a note of where it downloads to, and what it's called. Some add-on files may have silly names like 'latest-234.xpi', which is not very helpful when you're trying to find it later on.

Open the Add-ons Manager tab in Thunderbird. There's a button to the left of the search box. Click this and select Install Add-on From File… from the subsequent menu.

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


  • Open the add-ons manager (click the menu button and then Add-ons).
  • Drag your downloaded XPI file to the Add-ons 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 Manager tab displayed. Drag the link directly from the browser onto Thunderbird's Add-ons Manager tab. The main advantage of this method is that you don't need to actually save a copy of the add-on to your hard disk before it is installed.
