Have a look here:

latest win32 version 3.3 "classic" is freeware for personal use.
will be set up as local proxy for any browser you have in their so-called
"configure free" mode.
restrictions asfaik :
only understands HTTP1.0, so opening more than 4 connections per server is useless.
what it can do:
URI filtering (full paths)
web bugs filtering
knows ad img sizes, but can be trained to detect any format you want
block many js-"tricks" (onLoad, onBlur or popUp)
don't send referrer
distinct good/bad cookies
