Firefox Developer Tools - Highlighting elements on hover?

Is this possible? Chrome Dev Tools and Firebug both have this feature. Firefox Dev Tools only shows elements ON CLICK, but not on hover.

Solution

I don't think currently there is any option for that. But from Firefox 29 onwards this is possible.

From the docs:

From Firefox 29, the Inspector is no longer locked on the selected element: as you move the mouse around the markup in the HTML pane, the dotted border is shown around the corresponding element.
