Firefox Aurora is the equivalent of ChromeOCOs cutting-edge Dev, which means itOCOs definitely not for the average user. ItOCOs effectively an alpha build of the next version of Firefox OCo more stable than the nightly builds produced for developers, but still a long way off the relative stability of beta versions, never mind a final release. Make sure your computer is backed up before installing this, but once done, you can install it and get an early glimpse into the future of the Firefox browser.

The Firefox browser is created by Mozilla, a non-profit organization whose mission is to promote openness, innovation and opportunity on the Web.
