Developers behind the AdBlock browser extension have released a version for the Opera Browser.

AdBlock let web users block advertisements on web pages on their computers.

App description:

Block all advertisements on all web pages, including Facebook, YouTube, and Hulu. It works automatically: just click “Add to Opera,” then visit your favorite website. All ads will be gone — even those annoying video and popup ads! :) And if you’re feeling advanced, you can easily create your own filters, subscribe to arbitrary lists, disable AdBlock on a specific site, and much more. It’s translated into dozens of languages.
