Internet Explorer 9: An Early Look

By | March 20, 2010

No Windows XP Allowed!Speed and standards. Those two words sum up the goals of Microsoft’s just-released Platform Preview of its upcoming Internet Explorer 9 browser. I have to stress that there’s a good reason for calling it a “platform preview” rather than a “beta”—the code you can download from is not a full browser program by a long shot—there’s no Back button, let alone bookmark manager, history feature, toolbars, or any of the other features we’ve come to expect in modern Web browsers. So this hands on will be shorter than most, simply because there’s not much in the way of “user interface” or other goodies to talk about. But there’s still plenty to look at in terms of performance and standards support. And, from what we can see so far, it looks like Microsoft is on the right track.

The first thing you notice (beside download links) when you go to the home page for the Internet Explorer 9 Platform Preview are links to speed and standards tests both from Microsoft and from the outside world. That’s noteworthy, since the previous versions of the browser weren’t known for speed or adherence to standards. So, that’s a hopeful sign. And, in fact, the first results of my testing yielded impressive advances over Internet Explorer 8 in both performance and standards support. Most sites load more snappily than in IE8, and in some cases than in IE’s competitors. But this engine can’t claim top honors in performance and standards support just yet. Chrome and Opera still lead on a popular JavaScript benchmark, and Firefox supports more HTML 5, at the moment.

One note about running the Preview: Don’t try installing in on any nearly-decade-old operating systems (I’m looking at you, XP): If you do, you’ll get to a dialog stating “Windows Internet Explorer Platform Preview does not support any operating system earlier than Windows Vista SP2.” And of course, don’t even think about versions for non-Windows operating systems. IE General Manager Dean Hachamovitch told me that Mac and Linux versions weren’t currently in the company’s plans….
