MDN’s new design is in Beta! A sneak peek:

Highlight and inspect DOM nodes

This feature isn't yet supported in the new debugger. If you need to use it, you can, for now, switch back to the old debugger by visiting about:config and setting the "" preference to false.

To see the docs for the old debugger, please visit Debugger (before Firefox 52).

If you hover over a DOM node in the Variables pane, it will be highlighted in the page.

Also, a target icon will appear next to the variable. If you click on this target, the Inspector will open with this DOM element selected.
