I've been using this for years. It's the first thing I install in a new device after I install a fresh Firefox. I'm really surprised there are so few users, but there's no accounting for taste I reckon, either mine or theirs. Anyway, Dirtyco is real easy on the eyes and doesn't make changes to menus so you don't even recognize a function or page you're on. I recommend it, but with only 5 users as of this writing, I doubt anyone's gonna even see this review, but there ya go, I did finally get around to reviewing it.
