Can I simply ask 'why'? It seems like if Firefox has no method of guaranteeing that an add will be placed, there is no financial gain for the mozilla foundation.

Why would you even perceptually compromise user privacy. You have to realize there are many using your browser with expectations of privacy. If you perceptually damage this notion, you're going to loose mind share.

If this goes into firefox, I'll be looking for an alternative.
