I like the idea behind this extension, and it does what it says. It's also quite fun to watch it in action.

However, the settings panel could use a bit of love to be as usable and convincing as AdNauseum: The query list can't be closed, and the buttons change size when clicked making the text jump around, and some of these size-changing buttons need to be double-clicked very fast to work at all.

The link in the bottom of the settings panel to the Forbes article about DHS keywords is 404ing.
