Internet Explorer 9 Compatibility Results Are In

You can now check out the Cross-browser Test Results Summary for Microsoft’s Internet Explorer 9 here. Or why now take the IE 9 Test Drive if you dont want to see the data, and then have a nice read on Solutions for Virtualizing Internet Explorer to learn how to create a virtual operating environment in which you can run earlier versions of IE. 😉

This website contains several collections of new test pages that we developed in conjunction with the World Wide Web Consortium (W3C) working groups. These 192 test pages have been updated based on feedback and now include some new HTML5 test pages.

We respect how challenging it is to build one page that works the same in every browser as the technology advances and customer expectations rise. We have created these tests (and welcome your feedback!) to help web developers see if a browser supports what they are trying to do before they depend on it. Because there are ambiguities and options in any specification, there may be cases where some browsers behave differently. The Internet Explorer team remains committed to making the same standards-based markup work across browsers. This is why we are contributing these new test cases to the appropriate web standards working groups at the W3C.

There are two tables below. The first table is a summary of the test results with the May 2010 IE Platform Preview and each of the major shipping browsers running on Windows. The table at the bottom of this page provides details and links to each of the new test cases we submitted to each appropriate W3C working group to help the web become more interoperable.

I want to thank the members in the W3C working groups that helped us develop these tests, the community members for providing valuable feedback on the tests, as well as the engineers on the IE team that made these possible.
