The new Opera (v.6) is not only the fastest browser I’ve ever used, it finally works the way you want it to. Unlike earlier versions, the new Opera follows the well established “independent window” model just like all other Windows/*NIX/MacOS X apps. This means that Opera allows its windows to exist on their own rather than trapping them inside one cramped, cumbersome “parent” window.
At long last, the world is free to browse the web quickly and correctly. It’s worth your time, especially if you’d like to see how the web really looks.
