What are Opera extensions?
Extensions in Opera is a way for you to easily add new functionality to your Opera browser experience. Developers can easily create extensions using open standards (HTML5, CSS,JavaScript) and supported APIs.

Some extensions have user interface elements, but not all. An extension can for example add a button next to the Google Search field with a popup menu when you click on it. Other extensions don’t have user interfaces at all, but run in the background.
