Firefox OS Simulator is a test environment for Firefox OS. Use it to test your apps in a Firefox OS-like environment that looks and feels like a mobile phone.
Once the simulator tab is opened or the simulator is switched to "On" OS X complains that firefox has unexpectedly quit. Here's a gist of my crash data, for what it's worth: https://gist.github.com/tofumatt/7227448
