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.
Load up the simulator and flick to the right so the list of apps are displayed (not the marketplace).
Click on 'HERE maps' and it comes up with a list of files in the app rather than loading the app
Clicking the home button causes the HERE Maps icon to display like it has been dragged and one time it ended up in the mode where you can remove icons and move them around.
