- <h3 class="SECT2"><a name="WHO-USES" id="WHO-USES">1.1. Who should give <span class="APPLICATION">Privoxy</span>
- a try?</a></h3>
- <p>Anyone who is interested in security, privacy, or in finer-grained control over their web and Internet
- experience.</p>
- </div>
- <div class="SECT2">
- <h3 class="SECT2"><a name="BESTCHOICE" id="BESTCHOICE">1.2. Is Privoxy the best choice for me?</a></h3>
- <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=
- "http://en.wikipedia.org/wiki/Regular_expressions" target="_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>

- <div class="SECT2">
- <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>
- <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>
- </div>
- <div class="SECT2">
- <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>
- </li>
- </ul>

- <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 server on a network?</a></h3>
- <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 proxy for my LAN</a> below.</p>
- </div>
- <div class="SECT2">
- <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>
- </div>
- <div class="SECT2">
- <h3 class="SECT2"><a name="LICENSE" id="LICENSE">1.14. Is there is a license or fee? What about a warranty?
- Registration?</a></h3>
- <p><span class="APPLICATION">Privoxy</span> is free software and licensed under the <a href=

- <p>There is <span class="emphasis"><i class="EMPHASIS">no warranty</i></span> of any kind, expressed, implied or

- </div>
- <div class="SECT2">
- <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>
- </div>
- <div class="SECT2">
- <h3 class="SECT2"><a name="OTHERADS" id="OTHERADS">1.16. Can I use 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="APPLICATION">Privoxy</span> in conjunction with other
- ad-blocking products, and this could conceivably cause undesirable results. It might be better to choose one
- software or the other and work a little to tweak its configuration to your liking.</p>

+CLASS="APPLICATION"
+>Privoxy</SPAN

+ </P
+><P
+> One of <SPAN
+CLASS="APPLICATION"
+>Privoxy's</SPAN

+ strengths is that it is highly configurable giving you the ability to

+>
+ 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

+ But there are areas where configuration is done using a
+ <A

+ is a service, based on a software such as <SPAN

+>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/)

+ a registered trademark of Junkbusters Corporation.
+ There were, however, no objections from Junkbusters Corporation to the
+ <SPAN

+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.</P

+This does not sound very scientific.</A
+></H3

+> 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.

+NAME="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

+>Privoxy</SPAN
+> (see the <A
+HREF="installation.html#FIRSTSTEP"
+>Installation section below</A
+>).</P
+><P

+ would certainly benefit by customizing <SPAN
