I stumbled upon this the other day and have been using it at home the last several days. It seems pretty neat as it is a triple engine browser (works as an IE type browser, Mozilla browser, and Chrome) and you can change between the engines right at the top of the browser.
In the FF type engine mode, most FF addons are usable in the Lunascape browser (at least the ones I have tried so far, which isn't many yet). As I get used to it, I kinda like it. It has a few things I don't like about it, but for the most part it seems pretty good.
If anyone wants to try it out, you can grab it (and read about it) here:
