Mozilla Add-ons is the official Mozilla Foundation website to act as a repository for add-ons for Mozilla software, including Mozilla Firefox, Mozilla Thunderbird, SeaMonkey, and Mozilla Sunbird. These add-ons include extensions, themes, dictionaries, search bar "search engines," and plugins. Because of its domain name, the site is informally also known as AMO.[2]
