Lunascape is the world's most versatile browser, combining the engines from Firefox, Google Chrome and Internet Explorer into a single application.

This gives you an immediate compatibility advantage. If a site doesn't seem to display properly when you view it with the IE engine, say, then you can redisplay it with the Firefox engine in a couple of clicks. Or, if you're at a JavaScript-heavy site, then choose Chrome and benefit from its extra performance.

Lunascape works with most Firefox addons and IE plugins, too. A simple wizard will import your existing favourites and add-ons, then you can install more as you like.

The program isn't just about IE, Firefox and Chrome, though - it has many interesting features of its own. Lunascape comes with many bookmarklets, supports scripts for more advanced automation tasks, includes mouse gestures, a pop-up blocker and built-in RSS reader, allows you to set the user agent string, and is generally very configurable.

And yet, despite all the extras, Lunascape still performs very well. The core of the program requires little in the way of memory or system resources, and the browser remained snappy and responsive throughout all our tests.
