At the Up North Web, Opera announced that Opera 11 will feature an extension system. "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.

Extensions will be based on the W3C Widget specifications and this is being considered for an Open Standard effort."

The first cut will offer APIs for interacting with certain bits of the Opera 11 UI , tab and window functions, callouts, and injectable JavaScript. Opera will base their extensions system upon the W3 Widget specs -- not surprising, given Opera's history of standards support.

The Opera 11 alpha download isn't available yet, but you'll be able to get it at www.opera.com/browser/next once it's ready.
