Update Scanner

Hi,
Great extension. It's one of my most frequently used.

Are you aware of this?
Three Firefox Add-Ons are Faulty!
http://www.pc1news.com/news/0948/three-firefox-add-ons-are-faulty.html

Update Scanner is mentioned as one vulnerable.
I've disabled Update Scanner until I learn more which really throws a wrench into things for me.
I use it to keep an eye out for spam on several sites that I'm a moderator for not to mention 40 other things.

Thanks.
Ken
