I'm so excited right now to write apps for Firefox OS, the hottest mobile operating system of Mozilla.
- Everything is here: https://developer.mozilla.org/en-US/docs/Mozilla/Firefox_OS
The only phone maker right now which produces phones that runs Firefox OS is Geekphone (a Spain company, http://www.geeksphone.com/), but all of the there Firefox OS powered phones were sold old in just a couple of hours after launch. So, I and so many other fan-boy all over the world cannot have a chance to buy it. So, the only thing I can do right now is write apps and test it on the Simulator.
