Test Websites For Compatibility Using IETester

All developers wish they could install multiple versions of Internet Explorer as every version is different from the other, and it’s real pain for developers to code and test their websites in every version of IE. There are many users of use IE6 as their primary browser, and since Vista gets IE7, it again renders websites differently than IE6. To top it all, we now have IE8, which again renders websites differently than any prior versions.

Some web services like Browsershots have been very useful to test websites in various version of different web-browsers. Recently, the release of IETester will make things much easier now. IETester is a free web-browser that allow you to have the rendering and javascript engines of IE8 beta 1, IE7, IE 6 and IE5.5 on Vista and XP, as well as the installed IE in the same process. Now you can test websites in various versions of IE, all at the same time in different tabs side by side.
