Must-have for Firefox Users Rated 4 out of 5 stars

I immediately put this on every computer I use; I'm not sure how I survived without it. I love being able to see my screen, and this makes it possible to minimize the toolbar-tangle at the top of my browser.

I gave it a nine because the toggle switches get a bit irritating for me; usually I have to go through all three "settings" to get it to go away. But it's worth those three clicks!

This review is for a previous version of the add-on (0.7.1).
