<h2 id="Connecting_the_Developer_Tools">Connecting the Developer Tools</h2>

<p>If you open the developer tools using <a href="/en-US/docs/Tools/Keyboard_shortcuts#Opening_and_closing_tools">keyboard shortcuts</a> 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.</p>

<p>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.</p>

<h2 id="Extending_the_devtools">Extending the devtools</h2>

<p>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.</p>
