Back in 2008 we wrote about a free tool called IETester that would let you test a webpage in a variety of Internet Explorer versions. Since that time Microsoft has rolled out new releases of the browser, and the developer of IETester has continued to add support for each one.
As it stands right now IETester works with IE5.5, IE6, IE7, IE8, IE9, and even the developer preview of IE10. Getting IETester to work with IE10 will take a few minutes, but there are only a few steps that mostly consist of copying a couple files.
If you haven’t used this application yet I’d recommend taking advantage of the “All IE Versions” button located on the main tab. When you click on this a popup will be displayed where you can select the different IE versions you want to test in, and then you enter in the URL to be tested. Once you’ve done that IETester will open a new tab for each different version of IE. Extremely handy for any web developer.
