DOM inspector for Firefox GUI (Chrome Document) using built-in Dev Tools

Is it possible to inspect the Firefox browser GUI using the new built-in Developer Tools?

I used to be able to do this with the old DOM Inspector by selecting File > Select Chrome Document. I could then click through the list of DOM nodes and the corresponding part of the Firefox browser interface would light up (e.g. toolbar buttons etc.).

I cannot seem to find a way to do this with the new built-in Firefox Developer Tools. The inspector only seems to inspect web site page content, and not the Firefox browser itself.

You will have to use the DOM Inspector for the Firefox browser user interface. As you have noticed, you can only use the Web Developer tools for a web page.


Thanks for the confirmation.

I just wanted to be sure that I wasn't overlooking the feature within the Dev tools.
