CSSVista is a free Windows application for web developers which lets you edit your CSS code live in both Internet Explorer and Firefox simultaneously.

The possibility of using IE and Firefox in the same windows while editing the CSS in real time is awesome. The bad thing about it is about that we can’t change between versions of IE, and support for more browsers would be great. Although that, this new version has code completion and element outlining to help you see side-by-side all block elements in both browsers.
