This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.
WebIDE allows you to connect the Firefox Developer Tools to a number of other browsers, such as Firefox for Android. 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.
