Mozilla yesterday announced the launch of a new Firefox OS Simulator.

Mozilla acknowledged that the third version of the simulator is "a bit rough around the edges," but decided to release it to give users the chance to give feedback and contribute fixes.

Firefox OS is Mozilla's upcoming mobile operating system. Since late last year, the organization has been offering simulators showcasing its functionality and giving users the chance to try it out. As with previous versions, Firefox OS Simulator 3.0 is available to Windows, Linux, and OS X users, and runs as an extension in the Firefox browser.

The latest update adds a host of features to the simulator, including a Push to Device offering that automatically pushes apps installed on one Firefox OS device to another by being connected to USB. The updated simulator also includes rotation-simulation features, geolocation API, and new versions of the Firefox user interface, Gaia.

The Firefox OS Simulator can be downloaded from the Mozilla FTP server under its working name, r2d2b2g. After it's installed, users can access it through the Web Developer menu in the browser.

Details about Apple's 'spaceship' campus from the drone pilot who flies over it

MyithZ has one of the most popular aerial photography channels on YouTube. With the exception of revealing his identity, he is an open book as he shares with CNET's Brian Tong the drone hardware he uses to capture flyover shots of the construction of Apple's new campus, which looks remarkably like an alien craft.
