Just what I'm looking for. Others who use my PC won't know that I've blocked some sites which they use. Love it... :D

I just loaded this add-on and specified several sites and none of them have been blocked after several restarts of Firefox. The doc that shows up in the Option pop-up is truncated thus it whole Whitelist discussion is lost. I loaded another add-on on my wife's XP machine that works great - wish I could find it again!

It loads the target site's page first then quickly loads a blank page. It should not even request a page from a blocked site.
