Connecting the Developer Tools

If you open the developer tools using keyboard shortcuts or the equivalent menu items, they'll target the document hosted by the currently active tab. But you can attach the tools to a variety of other targets, too, both within the current browser and in different browsers or even different devices.

Debug add-ons, content tabs, and workers running in the browser.

Connecting to iframes

Connecting to other browsers

Debugging the browser

By default, the developer tools are attached to a web page or web app. But you can also connect them to the browser as a whole. This is useful for browser and add-on development.

Browser Console
See messages logged by the browser itself and by add-ons, and run JavaScript code in the browser's scope.
Browser Toolbox
Attach the Developer Tools to the browser itself.

Extending the devtools

The developer tools are designed to be extensible. Firefox add-ons can access the developer tools and the components they use to extend existing tools and add new tools. With the remote debugging protocol, you can implement your own debugging clients and servers, enabling you to debug websites using your own tools or to debug different targets using the Firefox tools.
