I am wondering if this will go anywhere. It seems to me that if anyone would be willing to do this it would actually be the Chrome team, not Mozilla. Mozilla currently lacks the market share to pull this off, and lately their moves have been more targeted in a different direction.

Having said that, I am really happy others are thinking along the same lines as I: HTTP should be relegated to a legacy protocol and the warnings need to very similar to what you get when accessing a site secured by a self-signed cert.
