Firebug used to be the top development tool for web design, but now most major browsers have their own advanced Developer Tools built in. However, there are still times when I find it more convenient to include the Firebug script when working with code on JSFiddle, especially when debugging or examining HTML attributes and classes.
However, adding Firebug Lite to a JSFiddle project can sometimes cause it to block the output frame, taking up too much space on the screen.

Is there a way to include Firebug Lite in a minimized mode on JSFiddle, similar to the bottom horizontal bar or small square shown in this image?
