Vulnerabilities are patched frequently enough. If there is a kind of behavior you want to prevent, write a plugin for it. Noscript and Greasemonkey are pretty handy for most things. The worst things a browser can do come from javascript, so having a whitelist is useful. Remove anyone from your whitelist that is engaging in behavior you disapprove of. I don't let facebook run scripts on my machines because I disagree with their philosophy of selling user data to the highest bidder, and tracking everything users do. That's too intrusive so I simply disallow them access. No site that calls in too many javascript packages is given any privs on my computer.
