Firefox OS apps are similar to websites or web apps and are built with standard web technologies such as HTML, JavaScript, and CSS. They can be accessed through a web browser and can also be installed on devices for working offline.

The list of web APIs contained within the WEBAPP file allows you to make decisions about apps before installing them. WEBAPP files are necessary in order to publish an app to the Firefox Marketplace.
