Lunascape is a new web browser that handles all three major web rendering engines — Firefox’s Gecko, Internet Explorer’s Trident and WebKit (which is used by Safari and Chrome).
Lunascape 5 Alpha is Windows-only and the first English version of the browser.
This is how Lunascape works: Users can toggle between rendering engines by either right-clicking tabs or by clicking on the engine switcher button on the bottom left of the screen. If you have figured out which engine works best for a page, Lunascape lets you force the page to use that engine for future visits via a pull down menu.
I will get our PLDs here to do some testing and it might help us in developing better websites.
