I just came across this Free Web Browser Avant Browser which runs on top of Microsoft Internet Explorer and provides a compact interface to Web Browser. Instead of multiple windows of Internet Explorer, it has multi-tabbed interface and is really cool. Moreover, it has Google Search Engine builtin, which provides an additional advantage to the tool.
What's more? Avant Browser is a free tool too. Avant Browser is a free download from http://www.avantbrowser.com/
