Wow, I can’t believe this day has come! After so many years of developers wishing for a better browser from Microsoft, one that was more consistent with web standards and would allow them to develop cross-browser websites leveraging the same markup, today marks the day that developers finally have that browser; Internet Explorer 9 Beta. It’s an important day because this release, although just a beta, is the culmination of a lot of effort and most importantly, listening, by the Internet Explorer team.
While the Internet Explorer browser has enjoyed widespread adoption by consumers, it hasn’t always been viewed fondly by the development community. The important work of building cross-browser compliant websites has often been cumbersome, due in part to differing interpretations of browser APIs in previous versions of Internet Explorer. The differences forced developers, myself included, to find workarounds for functionality that, in many cases, had a clearly defined standard behavior.
HTML5, CSS3, DOM
With Internet Explorer 9, there’s been a concerted effort by Microsoft to focus on standards-based functionality that will ease cross-browser development while providing the features needed to build rich and immersive websites. Take, for example, IE9’s support for many of the features of HTML5 and CSS3, the specifications which are defining the future of the web. By including support for features such as Canvas, video, @font-face, CSS3 media queries, SVG and many others, we now have a rich base to provide more compelling experiences to end users. In addition, by ensuring that these features are conformant to the defined specifications, the sites we build should work with any browser that also supports those specifications.
To take it a step further, the IE team has enhanced the performance of many of the new HTML5 features by taking advantage of the GPU. This means that text, graphics and video will be substantially smoother and more responsive allowing websites to perform more like true applications.
And at the DOM level, important changes have been made to be consistent with the defined specifications making it easier to whittle down browser-specific code. For example, support for the W3C DOM Events specification (addEventListener & removeEventListener) in place of the proprietary IE model (attacheEvent & detachEvent) has been one of the most welcomed changes to IE9 as has the introduction of getElementsByClassName, supported for some time in the DOM Level 2 specification and now available in IE9.
Updated Developer Tools
The new Console tab is a welcome addition providing the ability to inspect script easily as well as receive important page-specific error and warning messages.

Of the new features, the one that I’m most excited about is the network traffic inspector, mainly because the bulk of my application development involves Ajax-based requests.
IE Developer Tools – Network Performance of Specific Assets
IE Developer Tools – Network Request Information
I can now do such things as determine load times of specific assets or inspect my request/response headers, cookies and return values without the need for breaking out of the browser to a 3rd party application such as Fiddler or Charles.
Get to Using it Today
A lot of effort has gone into making Internet Explorer 9 Beta a better browser. There’s certainly more work to be done but the fact that we now have a version of IE that provides standards-based functionality and allows us to use the same markup across browsers is pretty hot.
To really appreciate what you can build with IE9, though, you need to just start digging into it. Microsoft has created the following sites to give developers the knowledge and inspiration they need to leverage IE9 to its fullest:
- Beauty of the Web – Explore all of the new features of Microsoft’s latest browser and check out the cool demos built using the advanced features of Internet Explorer 9 Beta
- Internet Explorer 9 Test Drive – This site breaks down the new, advanced features of Internet Explorer 9 Beta and lets you get a visual of what’s possible with each bit of functionality
- Internet Explorer Guide for Developers – The developer documentation you’ll need to learn how about the specifics of Internet Explorer 9 Beta
It feels great to know that we’re on a path to being able to build truly feature-rich websites that will be easier to maintain and provide a more exciting experience to users. While we’ll still need to support older browsers for some time, the fact that all the major browser vendors are heading in the same direction is going to allow us to build some truly amazing things. I can’t wait!
You realise of course that if you had been using either of FF or Chrome you would have had all that some time ago …
@Neal: Considering that I worked for Mozilla previously, I’m pretty in tune with what’s available to me. I’m happy that I now have similar functionality in all the browsers that I develop for.
Very nice looking. Looks like this will change it to a front line AJAX dev brower.
Thanks for this write up! I hope this is sign of things to come from Microsoft and the will continue to work with existing standards rather than trying to force the world to their own.
Windows XP is not going away in the next month or two.
IE9 doesn’t run on XP, yet Firefox and Chrome do.
The advent of IE9 magnifies the importance of
Microsoft tying their browser versions to a specific OS.
Maybe Microsoft has this all figured out in their business model,
but I really have to wonder how much longer this approach
to browser support is going to be sustainable.
I don’t think MS is going to force you to use this. If people are stubborn and stick with old OS’ like WinXp, then do it. I’m all for MS trying to shovel people out of the crap (not saying who’s crap it is).
