Privoxy (formerly JunkBuster)
version 3.0.13 beta has been released (6/14/2009). This is a web proxy
with advanced filtering capabilities for protecting privacy, filtering
web page content, managing cookies, controlling access, and removing
ads, banners, pop-ups and other obnoxious Internet junk. Thanks to
Matthew Murphy for the info.
