Nice idea, but VERY slow Rated 2 out of 5 stars

This is a nice idea, but I find that it has some horrible performance problems. When it's installed, using the Firebug DOM picker tool (the thing that lets you select an element to view directly from the page) sometimes throws the browser into a minute-long frenzy of 100% CPU use. I'll check back on it after a few revisions, but for now it's unusable.

This review is for a previous version of the add-on (0.7).
