tastes. Privoxy has application for both stand-alone systems and multi-user
networks.

1. General Information
1.1. What is this new version of Privoxy?
-The original Internet JunkbusterTM (tm) is a copyrighted product of Junkbusters
-Corporation. Development of this effort stopped some time ago as of version
-2.0.2. Stefan Waldherr started the ijbswa project on Sourceforge to rekindle
-development. Other developers subsequently joined with Stefan, and have since
-added many new features, refinements and enhancements. The result of this
-effort is Privoxy.

Privoxy has evolved from the Junkbuster 2.0.2 code base, and has advanced
significantly at this point.

Privoxy is the "Privacy Enhancing Proxy".
-There are possible legal complications from the continued use of the Junkbuster

-objections from Junkbusters Corporation to the Privoxy project itself, and
-they, in fact, still share our ideals and goals.)

-own right, especially now with the pending release of version 3.0.

But this should not be a big concern since the Privoxy configuration is very
flexible, and includes tools to help identify these types of situations so they
can be addressed as needed, allowing you to customize your installation. (See

But any operating system that runs TCP/IP, can conceivably take advantage of
Privoxy in a networked situation where Privoxy would run as a server on a LAN
confusion. You may want to save your old configuration files for future
reference. The configuration is substantially changed.

+or the other, but not both at this time :(

+
+-------------------------------------------------------------------------------
+
+3.14. How can I make Privoxy work with other proxies like Squid?
This can be done. See the user manual, which describes how to do this.
Since Privoxy sits between your web browser and the Internet, it can be
programmed to handle certain pages specially.
-With recent versions of Privoxy (version 2.9.x), you can get some information
-about Privoxy and change some settings by going to http://p.p/ or,
+With recent versions of Privoxy (version 2.9.x and greater), you can get some

equivalently, http://config.privoxy.org/ (Note that p.p is far easier to type
but may not work in some configurations. With the name change to Privoxy, this
-is changed from the previous http://i.j.b/ or earlier 2.9.x versions).
+is changed from the previous http://i.j.b/ and earlier 2.9.x versions).
These pages are not forwarded to a server on the Internet - instead they are
handled by a special web server which is built in to Privoxy.
If you have version 2.0.2, then the equivalent is http://example.com/
show-proxy-args (but you get far less information, and you should really
-consider upgrading to 2.9.x).
+consider upgrading to 2.9.14).
-------------------------------------------------------------------------------
4.4. Do you still maintain the blocklists?
-No. The format of the blocklists has changed significantly in the versions
-2.9.x. Once we have released the new stable version, v3.0, there will again be
-blocklists that you can update automatically.
+No, not by this name. The format of the blocklists has changed significantly in
+versions 2.9.x and later. This functionality is done by the "actions" file now.
+See next question ...
-------------------------------------------------------------------------------
4.5. How can I submit new ads?
-As of now, please discontinue to submit new ad blocking infos. Once we have
-released the new version, there will again be a form on the website, which you
-can use to contribute new ads.
+Beginning with Privoxy v2.9.14, missed ads and banners and other actions file
+problems, can be submitted by accessing "actions file feedback system" from
+http://p.p/
+
+This process does not work with earlier versions of Privoxy or Junkbuster.
+
+There will soon be regularly updated actions files posted. These will be
+announced on the ijbswa-announce list.
-------------------------------------------------------------------------------
4.6. How can I hide my IP address?
You cannot hide your IP address with Privoxy or any other software, since the
-server needs to know your IP address to send the answer to you.

+8.2. History
+
+Privoxy is evolved, and derived from, the Internet Junkbuster, with many
+improvments and enhancements over the original.
+
+Junkbuster was originally written by Anonymous Coders and Junkbusters
+Corporation, and was released as free open-source software under the GNU GPL.
+Stefan Waldherr made many improvements, and started the SourceForge project
+Privoxy to rekindle development. There are now several active developers
+contributing. The last stable release of Junkbuster was v2.0.2, which has now
