- <h3 class="SECT2"><a name="BESTCHOICE" id="BESTCHOICE">1.2. Is Privoxy

-
- <p><span class="APPLICATION">Privoxy</span> is certainly a good choice,
- especially for those who want more control and security. Those with the
- willingness to read the documentation and the ability to fine-tune
- their installation will benefit the most.</p>
-
- <p>One of <span class="APPLICATION">Privoxy's</span> strengths is that
- it is highly configurable giving you the ability to completely
- personalize your installation. Being familiar with, or at least having
- an interest in learning about <a href=
- "http://en.wikipedia.org/wiki/Http" target="_top">HTTP</a> and other
- networking protocols, <a href="http://en.wikipedia.org/wiki/Html"
- target="_top">HTML</a>, and <a href=

- "_top"><span class="QUOTE">"Regular Expressions"</span></a> will be a
- big plus and will help you get the most out of <span class=
- "APPLICATION">Privoxy</span>. A new installation just includes a very
- basic configuration. The user should take this as a starting point
- only, and enhance it as he or she sees fit. In fact, the user is
- encouraged, and expected to, fine-tune the configuration.</p>
-
- <p>Much of <span class="APPLICATION">Privoxy's</span> configuration can
- be done with a <a href="http://en.wikipedia.org/wiki/Web_browser"
- target="_top">Web browser</a>. But there are areas where configuration
- is done using a <a href="http://en.wikipedia.org/wiki/Text_editors"
- target="_top">text editor</a> to edit configuration files. Also note
- that the web-based action editor doesn't use authentication and should
- only be enabled in environments where all clients with access to
- <span class="APPLICATION">Privoxy</span> listening port can be
- trusted.</p>

- <h3 class="SECT2"><a name="PROXYMORON" id="PROXYMORON">1.3. What is a
- <span class="QUOTE">"proxy"</span>? How does Privoxy work?</a></h3>
-
- <p>A <a href="http://en.wikipedia.org/wiki/Proxy_server" target=
- "_top">web proxy</a> is a service, based on a software such as
- <span class="APPLICATION">Privoxy</span>, that clients (i.e. browsers)
- can use instead of connecting to web servers directly. The clients then
- ask the proxy to request objects (web pages, images, movies etc) on
- their behalf and to forward the data to the clients. It is a
- <span class="QUOTE">"go-between"</span>. For details, see <a href=
- "http://en.wikipedia.org/wiki/Proxy_server" target="_top">Wikipedia's
- proxy definition</a>.</p>
-
- <p>There are many reasons to use web proxies, such as security
- (firewalling), efficiency (caching) and others, and there are any
- number of proxies to accommodate those needs.</p>
-
- <p><span class="APPLICATION">Privoxy</span> is a proxy that is
- primarily focused on privacy enhancement, ad and junk elimination and
- freeing the user from restrictions placed on his activities. Sitting
- between your browser(s) and the Internet, it is in a perfect position
- to filter outbound personal information that your browser is leaking,
- as well as inbound junk. It uses a variety of techniques to do this,
- all of which are under your complete control via the various
- configuration files and options. Being a proxy also makes it easier to
- share configurations among multiple browsers and/or users.</p>

-
- <div class="SECT2">
- <h3 class="SECT2"><a name="OTHERSTUFF" id="OTHERSTUFF">1.4. Does
- Privoxy do anything more than ad blocking?</a></h3>
-
- <p>Yes, ad blocking is but one possible use. There are many, many ways
- <span class="APPLICATION">Privoxy</span> can be used to sanitize and
- customize web browsing.</p>
- </div>
-
- <div class="SECT2">
- <h3 class="SECT2"><a name="NEWJB" id="NEWJB">1.5. What is this new
- version of <span class="QUOTE">"Junkbuster"</span>?</a></h3>
-
- <p>A long time ago, there was the <span class="APPLICATION">Internet
- Junkbuster</span>, by Anonymous Coders and Junkbusters Corporation.
- This saved many users a lot of pain in the early days of web
- advertising and user tracking.</p>
-
- <p>But the web, its protocols and standards, and with it, the
- techniques for forcing ads on users, give up autonomy over their
- browsing, and for tracking them, keeps evolving. Unfortunately, the
- <span class="APPLICATION">Internet Junkbuster</span> did not. Version
- 2.0.2, published in 1998, was the last official release, available from
- Junkbusters Corporation. Fortunately, it had been released under the
- GNU <a href="http://www.gnu.org/licenses/old-licenses/gpl-2.0.html"
- target="_top">GPL</a>, which allowed further development by others.</p>
-
- <p>So Stefan Waldherr started maintaining an improved version of the
- software, to which eventually a number of people contributed patches.
- It could already replace banners with a transparent image, and had a
- first version of pop-up killing, but it was still very closely based on
- the original, with all its limitations, such as the lack of HTTP/1.1
- support, flexible per-site configuration, or content modification. The
- last release from this effort was version 2.0.2-10, published in
- 2000.</p>
-
- <p>Then, some <a href=
- "https://www.privoxy.org/user-manual/copyright.html#AUTHORS" target=
- "_top">developers</a> picked up the thread, and started turning the
- software inside out, upside down, and then reassembled it, adding many
- <a href=
- "https://www.privoxy.org/user-manual/introduction.html#FEATURES"
- target="_top">new features</a> along the way.</p>
-
- <p>The result of this is <span class="APPLICATION">Privoxy</span>,
- whose first stable version, 3.0, was released August, 2002.</p>
-
- <p>As of 2012 the Junkbusters Corporation's website
- (http://www.junkbusters.com/) has been shut down, but Privoxy is still
- actively maintained.</p>

- <h3 class="SECT2"><a name="WHYPRIVOXY" id="WHYPRIVOXY">1.6. Why
- <span class="QUOTE">"Privoxy"</span>? Why change the name from
- Junkbuster at all?</a></h3>
-
- <p>Though outdated, Junkbusters Corporation continued to offer their
- original version of the <span class="APPLICATION">Internet
- Junkbuster</span> for a while, so publishing our <span class=
- "APPLICATION">Junkbuster</span>-derived software under the same name
- would have led to confusion.</p>
-
- <p>There were also potential legal reasons not to use the <span class=
- "APPLICATION">Junkbuster</span> name, as it was (and maybe still is) a
- registered trademark of Junkbusters Corporation. There were, however,
- no objections from Junkbusters Corporation to the <span class=
- "APPLICATION">Privoxy</span> project itself, and they, in fact, shared
- our ideals and goals.</p>
-
- <p>The Privoxy developers also believed that there were so many
- improvements over the original code, that it was time to make a clean
- break from the past and make a name in their own right.</p>
-
- <p><span class="APPLICATION">Privoxy</span> is the <span class=
- "QUOTE">"<span class="emphasis"><i class="EMPHASIS">Privacy Enhancing
- Proxy</i></span>"</span>. Also, its content modification and junk
- suppression gives <span class="emphasis"><i class=
- "EMPHASIS">you</i></span>, the user, more control, more freedom, and
- allows you to browse your personal and <span class=
- "QUOTE">"<span class="emphasis"><i class="EMPHASIS">private</i></span>
- edition"</span> of the web.</p>
- </div>
-
- <div class="SECT2">
- <h3 class="SECT2"><a name="DIFFERS" id="DIFFERS">1.7. How does Privoxy
- differ from the old Junkbuster?</a></h3>
-
- <p><span class="APPLICATION">Privoxy</span> picks up where <span class=
- "APPLICATION">Junkbuster</span> left off. <span class=
- "APPLICATION">Privoxy</span> still blocks ads and banners, still
- manages <a href="http://en.wikipedia.org/wiki/Browser_cookie" target=
- "_top">cookies</a>, and still helps protect your privacy. But, most of
- these features have been enhanced, and many new ones have been added,
- all in the same vein.</p>
-
- <p><span class="APPLICATION">Privoxy</span>'s new features include:</p>
-
- <ul>
- <li>
- <p>Supports "Connection: keep-alive". Outgoing connections can be
- kept alive independently from the client.</p>
- </li>
-
- <li>
- <p>Supports IPv6, provided the operating system does so too, and
- the configure script detects it.</p>
- </li>
-
- <li>
- <p>Supports tagging which allows to change the behaviour based on
- client and server headers.</p>
- </li>
-
- <li>
- <p>Can be run as an "intercepting" proxy, which obviates the need
- to configure browsers individually.</p>
- </li>
-
- <li>
- <p>Sophisticated actions and filters for manipulating both server
- and client headers.</p>
- </li>
-
- <li>
- <p>Can be chained with other proxies.</p>
- </li>
-
- <li>
- <p>Integrated browser-based configuration and control utility at
- <a href="http://config.privoxy.org/" target=
- "_top">http://config.privoxy.org/</a> (shortcut: <a href=
- "http://p.p/" target="_top">http://p.p/</a>). Browser-based tracing
- of rule and filter effects. Remote toggling.</p>
- </li>
-
- <li>
- <p>Web page filtering (text replacements, removes banners based on
- size, invisible <span class="QUOTE">"web-bugs"</span> and HTML
- annoyances, etc.)</p>
- </li>
-
- <li>
- <p>Modularized configuration that allows for standard settings and
- user settings to reside in separate files, so that installing
- updated actions files won't overwrite individual user settings.</p>
- </li>
-
- <li>
- <p>Support for Perl Compatible Regular Expressions in the
- configuration files, and a more sophisticated and flexible
- configuration syntax.</p>
- </li>
-
- <li>
- <p>GIF de-animation.</p>
- </li>
-
- <li>
- <p>Bypass many click-tracking scripts (avoids script
- redirection).</p>
- </li>
-
- <li>
- <p>User-customizable HTML templates for most proxy-generated pages
- (e.g. "blocked" page).</p>
- </li>
-
- <li>
- <p>Auto-detection and re-reading of config file changes.</p>
- </li>
-
- <li>
- <p>Most features are controllable on a per-site or per-location
- basis.</p>
- </li>
-
- <li>
- <p>Many smaller new features added, limitations and bugs
- removed.</p>

- <div class="SECT2">
- <h3 class="SECT2"><a name="WHATSANAD" id="WHATSANAD">1.8. How does
- Privoxy know what is an ad, and what is not?</a></h3>
-
- <p><span class="APPLICATION">Privoxy</span>'s approach to blocking ads
- is twofold:</p>
-
- <p>First, there are certain patterns in the <span class=
- "emphasis"><i class="EMPHASIS">locations</i></span> (URLs) of banner
- images. This applies to both the path (you wouldn't guess how many web
- sites serve their banners from a directory called <span class=
- "QUOTE">"banners"</span>!) and the host (blocking the big banner
- hosting services like doublecklick.net already helps a lot).
- <span class="APPLICATION">Privoxy</span> takes advantage of this fact
- by using <a href="../user-manual/actions-file.html#AF-PATTERNS" target=
- "_top">URL patterns</a> to sort out and block the requests for things
- that sound like they would be ads or banners.</p>
-
- <p>Second, banners tend to come in certain <span class=
- "emphasis"><i class="EMPHASIS">sizes</i></span>. But you can't tell the
- size of an image by its URL without downloading it, and if you do, it's
- too late to save bandwidth. Therefore, <span class=
- "APPLICATION">Privoxy</span> also inspects the HTML sources of web
- pages while they are loaded, and replaces references to images with
- standard banner sizes by dummy references, so that your browser doesn't
- request them anymore in the first place.</p>
-
- <p>Both of this involves a certain amount of guesswork and is, of
- course, freely and readily configurable.</p>
- </div>
-
- <div class="SECT2">
- <h3 class="SECT2"><a name="MISTAKES" id="MISTAKES">1.9. Can Privoxy
- make mistakes? This does not sound very scientific.</a></h3>
-
- <p>Actually, it's a black art ;-) And yes, it is always possible to
- have a broad rule accidentally block or change something by mistake.
- You will almost surely run into such situations at some point. It is
- tricky writing rules to cover every conceivable possibility, and not
- occasionally get false positives.</p>
-
- <p>But this should not be a big concern since the <span class=
- "APPLICATION">Privoxy</span> 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.
- (<a href="trouble.html#BADSITE">See the Troubleshooting section
- below</a>.)</p>
- </div>
-
- <div class="SECT2">
- <h3 class="SECT2"><a name="CONFIGORNOT" id="CONFIGORNOT">1.10. Will I
- have to configure Privoxy before I can use it?</a></h3>
-
- <p>That depends on your expectations. The default installation should
- give you a good starting point, and block <span class=
- "emphasis"><i class="EMPHASIS">most</i></span> ads and unwanted
- content, but many of the more advanced features are off by default, and
- require you to activate them.</p>
-
- <p>You do have to set up your browser to use <span class=
- "APPLICATION">Privoxy</span> (see the <a href=
- "installation.html#FIRSTSTEP">Installation section below</a>).</p>
-
- <p>And you will certainly run into situations where there are false
- positives, or ads not being blocked that you may not want to see. In
- these cases, you would certainly benefit by customizing <span class=
- "APPLICATION">Privoxy's</span> configuration to more closely match your
- individual situation. And we encourage you to do this. This is where
- the real power of <span class="APPLICATION">Privoxy</span> lies!</p>
- </div>
-
- <div class="SECT2">
- <h3 class="SECT2"><a name="LAN" id="LAN">1.11. Can Privoxy run as a

-
- <p>Yes, <span class="APPLICATION">Privoxy</span> runs as a server
- already, and can easily be configured to <span class=
- "QUOTE">"serve"</span> more than one client. See <a href=
- "configuration.html#LANCONFIG">How can I set up Privoxy to act as a

- <h3 class="SECT2"><a name="BROWSERS2" id="BROWSERS2">1.12. My browser
- does the same things as Privoxy. Why should I use Privoxy at
- all?</a></h3>
-
- <p>Modern browsers do indeed have <span class="emphasis"><i class=
- "EMPHASIS">some</i></span> of the same functionality as <span class=
- "APPLICATION">Privoxy</span>. Maybe this is adequate for you. But
- <span class="APPLICATION">Privoxy</span> is very versatile and
- powerful, and can probably do a number of things your browser just
- can't.</p>
-
- <p>In addition, a proxy is good choice if you use multiple browsers, or
- have a LAN with multiple computers since <span class=
- "APPLICATION">Privoxy</span> can run as a server application. This way
- all the configuration is in one place, and you don't have to maintain a
- similar configuration for possibly many browsers or users.</p>
-
- <p>Note, however, that it's recommended to leverage both your browser's
- and <span class="APPLICATION">Privoxy's</span> privacy enhancing
- features at the same time. While your browser probably lacks some
- features <span class="APPLICATION">Privoxy</span> offers, it should
- also be able to do some things more reliably, for example restricting
- and suppressing JavaScript.</p>
- </div>
-
- <div class="SECT2">
- <h3 class="SECT2"><a name="WHYTRUST" id="WHYTRUST">1.13. Why should I
- trust Privoxy?</a></h3>
-
- <p>The most important reason is because you have access to <span class=
- "emphasis"><i class="EMPHASIS">everything</i></span>, and you can
- control everything. You can check every line of every configuration
- file yourself. You can check every last bit of source code should you
- desire. And even if you can't read code, there should be some comfort
- in knowing that other people can, and do read it. You can build the
- software from scratch, if you want, so that you know the executable is
- clean, and that it is <span class="emphasis"><i class=
- "EMPHASIS">yours</i></span>. In fact, we encourage this level of
- scrutiny. It is one reason we use <span class=
- "APPLICATION">Privoxy</span> ourselves.</p>

- <h3 class="SECT2"><a name="SPYWARE" id="SPYWARE">1.15. Can Privoxy
- remove spyware? Adware? Viruses?</a></h3>
-
- <p>No, at least not reliably enough to trust it. <span class=
- "APPLICATION">Privoxy</span> is not designed to be a malware removal
- tool and the default configuration doesn't even try to filter out any
- malware.</p>
-
- <p><span class="APPLICATION">Privoxy</span> could help prevent contact
- from (known) sites that use such tactics with appropriate configuration
- rules, and thus could conceivably prevent contamination from such
- sites. However, keeping such a configuration up to date would require a
- lot of time and effort that would be better spend on keeping your
- software itself up to date so it doesn't have known
- vulnerabilities.</p>

- Privoxy with other ad-blocking software?</a></h3>
-
- <p><span class="APPLICATION">Privoxy</span> should work fine with other
- proxies and other software in general.</p>
-
- <p>But it is probably not necessary to use <span class=

+ <p>
+ A <a href="http://en.wikipedia.org/wiki/Proxy_server" target=
+ "_top">web proxy</a> is a service, based on a software such as
+ <span class="APPLICATION">Privoxy</span>, that clients (i.e.
+ browsers) can use instead of connecting to web servers directly.
+ The clients then ask the proxy to request objects (web pages,
+ images, movies etc) on their behalf and to forward the data to the
+ clients. It is a <span class="QUOTE">"go-between"</span>. For
+ details, see <a href="http://en.wikipedia.org/wiki/Proxy_server"
+ target="_top">Wikipedia's proxy definition</a>.
+ </p>
+ <p>
+ There are many reasons to use web proxies, such as security
+ (firewalling), efficiency (caching) and others, and there are any
+ number of proxies to accommodate those needs.
+ </p>
+ <p>
+ <span class="APPLICATION">Privoxy</span> is a proxy that is
+ primarily focused on privacy enhancement, ad and junk elimination
+ and freeing the user from restrictions placed on his activities.
+ Sitting between your browser(s) and the Internet, it is in a
+ perfect position to filter outbound personal information that your
+ browser is leaking, as well as inbound junk. It uses a variety of
+ techniques to do this, all of which are under your complete control
+ via the various configuration files and options. Being a proxy also
+ makes it easier to share configurations among multiple browsers
+ and/or users.

+ <a name="NEWJB">1.5. What is this new version of <span class=
+ "QUOTE">"Junkbuster"</span>?</a>
+ </h3>
+ <p>
+ A long time ago, there was the <span class="APPLICATION">Internet
+ Junkbuster</span>, by Anonymous Coders and Junkbusters Corporation.
+ This saved many users a lot of pain in the early days of web
+ advertising and user tracking.
+ </p>
+ <p>
+ But the web, its protocols and standards, and with it, the
+ techniques for forcing ads on users, give up autonomy over their
+ browsing, and for tracking them, keeps evolving. Unfortunately, the
+ <span class="APPLICATION">Internet Junkbuster</span> did not.
+ Version 2.0.2, published in 1998, was the last official release,
+ available from Junkbusters Corporation. Fortunately, it had been
+ released under the GNU <a href=
+ "http://www.gnu.org/licenses/old-licenses/gpl-2.0.html" target=
+ "_top">GPL</a>, which allowed further development by others.
+ </p>
+ <p>
+ So Stefan Waldherr started maintaining an improved version of the
+ software, to which eventually a number of people contributed
+ patches. It could already replace banners with a transparent image,
+ and had a first version of pop-up killing, but it was still very
+ closely based on the original, with all its limitations, such as
+ the lack of HTTP/1.1 support, flexible per-site configuration, or
+ content modification. The last release from this effort was version
+ 2.0.2-10, published in 2000.
+ </p>
+ <p>
+ Then, some <a href=
+ "https://www.privoxy.org/user-manual/copyright.html#AUTHORS"
+ target="_top">developers</a> picked up the thread, and started
+ turning the software inside out, upside down, and then reassembled
+ it, adding many <a href=
+ "https://www.privoxy.org/user-manual/introduction.html#FEATURES"
+ target="_top">new features</a> along the way.
+ </p>
+ <p>
+ The result of this is <span class="APPLICATION">Privoxy</span>,
+ whose first stable version, 3.0, was released August, 2002.
+ </p>
+ <p>
+ As of 2012 the Junkbusters Corporation's website
+ (http://www.junkbusters.com/) has been shut down, but Privoxy is
+ still actively maintained.

+ </p>
+ </li>
+ <li>
+ <p>
+ Modularized configuration that allows for standard settings and

+ <a name="WHATSANAD">1.8. How does Privoxy know what is an ad, and
+ what is not?</a>
+ </h3>
+ <p>
+ <span class="APPLICATION">Privoxy</span>'s approach to blocking ads
+ is twofold:
+ </p>
+ <p>
+ First, there are certain patterns in the <span class="emphasis"><i
+ class="EMPHASIS">locations</i></span> (URLs) of banner images. This
+ applies to both the path (you wouldn't guess how many web sites
+ serve their banners from a directory called <span class=
+ "QUOTE">"banners"</span>!) and the host (blocking the big banner
+ hosting services like doublecklick.net already helps a lot). <span
+ class="APPLICATION">Privoxy</span> takes advantage of this fact by
+ using <a href="../user-manual/actions-file.html#AF-PATTERNS"
+ target="_top">URL patterns</a> to sort out and block the requests
+ for things that sound like they would be ads or banners.
+ </p>
+ <p>
+ Second, banners tend to come in certain <span class="emphasis"><i
+ class="EMPHASIS">sizes</i></span>. But you can't tell the size of
+ an image by its URL without downloading it, and if you do, it's too
+ late to save bandwidth. Therefore, <span class=
+ "APPLICATION">Privoxy</span> also inspects the HTML sources of web
+ pages while they are loaded, and replaces references to images with
+ standard banner sizes by dummy references, so that your browser
+ doesn't request them anymore in the first place.
+ </p>
+ <p>
+ Both of this involves a certain amount of guesswork and is, of
+ course, freely and readily configurable.

+ <div class="SECT2">

+ <a name="MISTAKES">1.9. Can Privoxy make mistakes? This does not

+ <p>
+ Actually, it's a black art ;-) And yes, it is always possible to
+ have a broad rule accidentally block or change something by
+ mistake. You will almost surely run into such situations at some
+ point. It is tricky writing rules to cover every conceivable
+ possibility, and not occasionally get false positives.
+ </p>
+ <p>
+ But this should not be a big concern since the <span class=
+ "APPLICATION">Privoxy</span> 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

+ <p>
+ That depends on your expectations. The default installation should
+ give you a good starting point, and block <span class="emphasis"><i
+ class="EMPHASIS">most</i></span> ads and unwanted content, but many
+ of the more advanced features are off by default, and require you
+ to activate them.
+ </p>
