Extensions - Thunderbird

Extensions are small adds-ons that give new functionality to complement Thunderbird's built-in features, so that you can customize Thunderbird to fit your own individual needs.

Installation

Installing a Thunderbird extension is a two-step process. First, after finding the extension that you want to install, save it to your computer (right-click and choose "Save Link As...") in a convenient location. Second, in Thunderbird go to the "Tools" menu, select "Extensions", click the "Install" button, browse to the extension that you just downloaded, and click the Open/OK button.

After installing your extensions, it is a good idea to keep the downloaded files somewhere on your computer in case you need to install these extensions again in a new Thunderbird profile in the future.

Sources for Thunderbird extensions

• Mozilla Update: always a good place to start. But keep in mind that some extensions made for Thunderbird might not (yet) be listed at Mozilla Update. If you can't find what you want, try some of the sites listed below.
• The Extensions Mirror
• Mozdev Extension Room
• Extension-writers' own websites:
  • AusDilecce Extensions
  • Jeroen Peters' Thunderbird extensions
  • Maximum Extension (chuonthis)
• Extensions forum at MozillaZine: a good place to get a glimpse of new extensions being developed, or to try out new extensions before they become available at the sites listed above.
