Pharming?

I wonder if there exist any protection against pharming, which is reportedly the future of identity theft and fraud.

And as a side-note, I wonder how good and effective the built-in phishing protection of Firefox is.

There is an anti-pharming extension in Firefox. Netcraft is probably your best for Anti-phishing.

Nothing will be any good for blocking as regards Phorm/Webwise
