How do you start the Firefox OS Simulator from inside the Firefox browser?
I just downloaded and installed the Firefox OS Simulator . If I click on "Menu" and then "Add Ons" it is there - now how do I get it to run? double clicking on it does nothing other than to display product information. My objective is to run an app called "whatsapp" from inside the Firefox OS Simulator. (I have tried unsuccessfully to get that app to run from within 2 emulators).
