Despite the 1.0 status, Mozilla’s Hacks blog still refers to the Firefox OS Simulator as a “preview” — largely because Firefox OS itself is still in development. The Simulator, however, is much less buggy than the release I tested last month (and the problems with the Linux and Windows builds have been resolved).

If you’d like to get started building apps for Firefox OS, the Simulator now has an official page on Mozilla’s Add-Ons site. Once it’s installed and running you’ll get a preview of what Firefox OS will be like on a mobile device.
