The outline part doesn't show up in Safari, but that's because Safari
already highlights the focused field. The background color part works
though. Really, Safari's border is nicer than just a plain border.
Your plugin is adding a Safari feature to other browsers, and since it
doesn't break Safari, I'd say it "works" on Safari.

P.S. OSX+Parallels = Safari, IE6, IE7, FF/Opera Win/Mac/Linux. All at
the same time, all without rebooting. It has simplified cross platform
development immensely for me. </plug>
