I regularly purge tons of cookies from doubleclick, informit,
googlesyndication, ad nauseum that have been collected even through
privoxy. Unfortunately privoxy really should only be depended upon as
a SOCKS to HTTP proxy converter. It is not a reliable privacy tool

While I'm at it, let me strengthen this statement by saying that such
a filter for selective torrification is pretty much a necessity for
the simple reason that every Tor user *has* to do all the
countermeasures by hand anyway as-is if they ever turn Tor off (which
I imagine most of them do, esp during periods of network lag).

If an extension such as Foxyproxy can perform these tasks
automatically, and can be verified to be performing them correctly
each time, this is a vast improvement over everyone doing it by hand
(especially for Tor newbies).
