Trying to strip all identifying bits from your browser is a fool's errand. Strictly speaking, all web users are uniquely identified by the combination of IP address and the timestamp of an HTTP GET. The only reason that's not practically an identifier is that web sites don't have access to the ISP logs necessary to resolve ('192.0.2.0', 'www.example.com', 1354989355) back to you. The question you should be asking is how likely it is that the specific website you're visiting, as opposed to a third-party partner, is snooping your Chrome plugins so it can later resolve your identity against the databases of other websites that you've explicitly visited, who also snoop such data themselves, so that both businesses could identify the extreme minority of users who go to this much trouble to protect their privacy. You're much better off with that risk vs. having dozens of third-party cookies hovering around you.
