>One thought: Route all Firefox users through Tor relays by default, creating some security-through-obscurity. There are problems with that, of course, including the blacklisting of Tor relays from many sites. Sure this would accomplish that goal, but it's extremely unpractical. The Tor network is slow enough as it is, add millions more people and it'll grind to a halt. Plus all the issues of sites that rely on IP addresses for fraud detection and moderation (banning spammers, for example).
