Lunascape is a web browser capable of running any of the three major web rendering engines—Gecko (Firefox), WebKit (Safari/Chrome), and Trident (Internet Explorer). That means that each time you open a new tab or follow a link, you can tell Lunascape which engine you want to use to render the page. The idea, in theory, is that Lunascape gives you the benefits of each popular browser in one. For example, Lunascape gives you IE support for the few IE-only sites still out there and no-nonsense speed from WebKit or Gecko.
