The Firefox OS App Manager is a new developer tool available in Firefox 26 that greatly improves the process of building and debugging Firefox OS apps, either in the Simulator or on a connected device. Based on the Firefox OS Simulator add-on, it bridges the gap between existing Firefox Developer tools and the Firefox OS Simulator, allowing developers to fully debug and deploy their web apps to Firefox OS with ease.
