Lunascape is a Web browser that combines the engines of Internet Explorer (Trident), Firefox (Gecko) and Safari (WebKit) under one roof. Using the context menu a user can can quickly move between the engines for optimal representations of each Web page. Browser add-ons for Firefox can even be used.
Lunascape supports mouse gestures, tabbed browsing and RSS readers, tabs and an intelligent search bar. In addition can be subscribed to podcasts and various security settings.
Lunascape is stable in testing, and offers an interesting approach. Having three rendering engines under one roof is certainly interesting for web designers.
