Online privacy is dead... if you let it die.

I wish I had a better answer for you but I actually switched away from Chrome to use this extension. Not only do I not have any helpful plugin recommendations, I'm actually going to poke a few holes in two of your helpful recommendations (sorry). If anyone else has good plugin suggestions I would love to look at them myself.

RequestPolicy is the only plugin I've seen that actually preemptively blocks all third party requests. (I'd love to hear of more.) There is a request to get it ported over to Chromium, but that hasn't been done yet as far as I can tell. The extensions you listed are better than nothing, however none of them will achieve the same result as RequestPolicy.

Ghostery is probably the best of those plugins, but it's still blacklist instead of white-list basted. Working the way it's intended Ghostery can make requests you don't want made, and you will only find out those requests have been made after. It fails open. This is better than nothing, but I don't feel it's optimal.

Disconnect on the other hand, if I understand it correctly, does nothing. Despite honestly good intentions it does not actually protect your privacy at all, it only creates the illusion of protection. As Panopticlick showed cookies are the easy way to track you, not the only way. By removing cookies you remove one method of identification, but you do not actually become anonymous.

Finally, none of these protect against CSRF which is a nice secondary effect of RequestPolicy. Sorry I couldn't help more.
