IE Tester: Browser Compatibility Check for Internet Explorer Versions from 5.5 to 9

IE Tester (http://www.my-debugbar.com/wiki/IETester/HomePage)

I guess that the title explain clearly what this software does. IE Tester is a tool that I was very happy to discover when I was testing some websites for compatibilities. It delivers the right result for IE6 and IE7. I no longer need to create a virtual machine to run IE6 and it saves me countless times.

Try it, you won't regret it.
