Though the Windows 8 app (formerly known as metro) version of Firefox hasn’t been released yet, it is available for the intrepid few who are willing to deal with a bug or two. If you want to try it out, download and install the latest Nightly Build of Firefox. When you head to your Start screen, don’t expect to find a Firefox tile; the one you need is called Nightly.

Though that may be annoying, you’ll be getting an early glance at this software before most even know it exists. Original Source – Mozilla Support – How do I Install Windows 8 (Metro-style) Firefox?
