Extensions make it possible to add features and functionality to Opera that are not native to it. In contrast to Opera Widgets, extensions run in the browser, but their behavior and their appearance in the user interface vary widely; one extension may be in the form of a button while another extension runs in the background.
See the catalog to read about and choose from a wide range of extensions.
