It does seem to solve the problem of the idiotic light fonts on light background, which 20 year olds with excellent eyesight think is cool. I await the day they can't read a page because of their own code. One problem, though. The icon is right next to the URL and before the "bookmark this page" icon, and is apparently unmovable. I'd rather have it over with my other addons, which I keep to the right of the search bar. Right now it's cluttering my address bar.
