I've got some updates to the CCK Wizard, but they've been taking a back seat to other work. I've finally got them together in this new beta. You can download it here.This one has the ability to remove the add-on discovery UI as well as support for modifying the default click to play list (thanks to Nils Sprenger and Tim Stecher).
I'm releasing this on Friday of this week, so if you have problems, please let me know.
There have been sporadic reports of bookmarks not working and certificates not installing. If that happens to you, I can't debug it without the XPI, so please send that to me if you have the problem.
