LittleBrowse 

LittleBrowse is an open-source web browser based off the Internet Explorer engine. It is designed as a replacement for Internet Explorer, by retaining all of Internet Explorer's capability while creating a small, easy to use browser. After surfing the web for many years using Internet Explorer. They discovered that it had many flaws. For example, loading webpages that are large in size may result in Internet Explorer freezing. They discovered after spending some time in the Task Manager that Internet Explorer alone was using almost 50MB of space! With LittleBrowse, they have divided that memory usage in half, creating a faster, and in some cases, superior, browser.
