<div>{{ToolsSidebar}}</div><p>You can use the Firefox developer tools on your desktop to debug code running remotely: in a different process on the same device or on a completely different device. To do this you use Firefox to attach the <a href="/en-US/docs/Toolbox" title="/en-US/docs/Toolbox">Toolbox</a> to the remote process, and the Toolbox is then launched in its own window. At the moment the following tools support remote debugging:</p>
