One of the most annoying tasks I have to do when I’m developing a website is to test it in the many different browsers and in some cases, multiple versions of each.
Internet Explorer is the most difficult to test. Windows typically only allows one version of IE to be installed and no two versions will render a page the same. Add to this the frustration that a huge percentage of users still use Internet Explorer version 6 (Come on people, IE6 will be 8 years old this August!) and you’ve got a real problem on your hands.
I stumbled across IETester and I must say, it’s very good.
You can easily test a website using IE 5.5, 6, 7 and 8 (beta 2) to sort out all those alignment and rendering issues.
