"In March, Opera added native ad blocking to a developer edition of its browser. Now, the company has pushed that feature into general release, dramatically decreasing the load time of web pages at the expense of the advertising revenues that would normally be driven to the site.
Native ad blocking is available both as a browser for Windows PCs and the Opera Mini browser for Android. Blocking ads not only speeds up the overall browsing experience, according to Opera, but can also eliminate a significant chunk of data that must be downloaded by smartphone users to view a Web page."
