WebIDE allows you to connect the Firefox Developer Tools to a number of other browsers, including Firefox for Android, Chrome on Android, and Safari on iOS. See the Remote Debugging page for instructions on how to connect to a specific browser.
With WebIDE, you first set up one or more runtimes. A runtime is an environment in which you'll run and debug the app. A runtime could be a Firefox OS device connected to the desktop over USB (or over Wi-Fi since Firefox 39), or it could be a Firefox OS Simulator installed on the desktop itself.
Next, you create an app, or open an existing app. If you're creating a new app you can start with a template that includes the directory structure and the minimum boilerplate you need to get started, or a more complete template that shows how to use a privileged API. WebIDE shows your app's files in a tree, and you can edit and save them using a built-in source editor. Of course, you don't have to use the built-in editor: you can develop your app entirely outside WebIDE, and only use it for debugging.
