Connect Fonts for Safari 4+

A dud, so far

I upgraded Suitcase to Connect and downloaded this Safari plugin.
I can't seen to get it to work. The instructions prompt you to "Quit and Open Safari Extensions Preferences…"
I tried every possible interpretation of that message and the extension fails to show up in Safari Extension Preferences.
Half-baked?
