As promised last week, here's the first build with built-in Fraud Protection. It's a very early preview of the technology, so everything is not entirely done yet, some sites actually show up wrong (silly bug with CNET sites!), and the icons are kind of ugly. Even the version number is wrong Opera v9.1 build 8629

The Weekly Builds are snapshots, they are not as thoroughly tested as a Technology Preview or a Public Beta. You should only use these builds if you are not afraid of losing data (e-mail, bookmarks, anything) or crashing your computer.
