Rated 4 out of 5 stars

Basically required for anybody working with the firefox UI. Interface seems a bit half-baked sometimes, but it works well enough.

Should have a keyboard shortcut though, because some elements of the UI (alert popup for saving passwords, australis menu etc) disappear when they lose focus so it's impossible to select them.
A kind of workaround is to navigate via arrow keys and tab, but that goes against the simple point-and-click functionality..

Also, minor nitpick, but the icon doesn't show up well on dark backgrounds.

Amazingly useful for add-on development. Saves me a huge amount of time compared to bringing up the DOM inspector and searching for an item.

Convenient developer tool! Rated 5 out of 5 stars

I love this add-on. It's unbelievably convenient in its functionality working with DOM Inspector to reveal elements of a web page or browser UI. If you're writing userscripts, userstyles, or addons, you'll love this tool. Please keep up the excellent work.

This review is for a previous version of the add-on (4.03.20120929).
