SonSpring | Removing Dotted Links: "Fixing the Fox:
It is no secret, I love Firefox. I have been using it since the beta version of 0.8. Firefox 1.5 though, has a quirk that proves to be a minor irritation every time I use it. I am of course referring to the dotted outline that appears around every link. In versions previous to 1.5, the outline behaved similarly to Internet Explorer on Windows, wrapping exactly around clickable areas."
