But HTTPSB is only for Chrome? If so, meh.
Edit: I personally block domains in global rules which are rather ubiquitous: `google.com`, `twitter.com`, `facebook.com`, `linkedin.com`, `gravatar.com`, etc. I enable these narrowly using scopes only when on a related web sites. I am pretty confident this cripples severely the ability of these ubiquitous servers to track me, regardless of the browser used.
