Add-ons are software modules that add new functionality to Mozilla applications. They can add anything from a toolbar button to a completely new feature. They allow the application to be customized to fit the personal needs of each user if they need additional features, while minimizing the size of the application itself.
Mozilla software uses add-on as an inclusive term for a category of augmentation modules that are subdivided into plugins, extensions, themes, and search engines.
Plugins and extensions add new features to the browser, while themes change the look of the interface.
