+-------------------------------------------------------------------------------
+
+3.10. Why would anybody want to see a checkerboard pattern?
+
+This can be helpful for troubleshooting problems. It might also be good for
+anyone new to Privoxy so that they can see if their favorite pages are
+displaying correctly, and Privoxy is not inadvertently removing something
+important.
+
+-------------------------------------------------------------------------------
+
+3.11. I see large red banners on some pages that say "Blocked". Why and how do
+I get rid of this?
+
+These are URLs that match something in one of Privoxy's block actions (+block).
+It is meant to be a warning so that you know something has been blocked and an
+easy way for you to see why. These are handled differently than what has been
+defined explicitly as "images" (e.g. ad banners). Depending on the URL itself,
+it is sometimes hard for Privoxy to really know whether there is indeed an ad
+image there or not. And there are limitations as to what Privoxy can do to
+"fool" the browser.
+
+For instance, if the ad is in a frame, then it is embedded in the separate HTML
+page used for the frame. In this case, you cannot just substitute an aribitray
+image (like we would for a "blank" image), for an HTML page. The browser is
+expecting an HTML page, and that is what it must have for frames. So this
+situation can be a little trickier to deal with, and Privoxy will use the
+"Blocked" page.
+
+If you want these to be treated as if they were images, so that they can be
+made invisible, you can try moving the offending URL from the "+block" section
+to the "+imageblock" section of your actions file. Just be forewarned, if any
+URL is made "invisible", you may not have any inkling that something has been
+removed from that page, or why. If this approach does not work, then you are
+probably dealing with a frame (or "ilayer"), and the only thing that can go
+there is an HTML page of some sort.
+
+To deal with this situation, you could modify the "block" HTML template that is
+used by Privoxy to display this, and make it something more to your liking.
+Currently, there is no configuration option for this. You will have to modify,
+or create your own page, and use this to replace templates/blocked, which is
+what Privoxy uses to display the "Blocked" page.
+
+Another way to deal with this is find why and where Privoxy is blocking the
+frame, and diable this. Then let the "+image-blocker" action handle the ad that
+is embedded in the frame's HTML page.
+
+-------------------------------------------------------------------------------
+
+3.12. I cannot see all of the "Blocked" page banner. All I see is a bright red
+square.
+
+There is not enough space to fit the entire page. Try right clicking on the
+visible, red portion, and select "Show Frame", or equivalent. This will usually
+allow you to see the entire Privoxy "Blocked" page, and from there you can see
+just what is being blocked, and why.
+
+-------------------------------------------------------------------------------
+
+3.13. Can Privoxy run as a service on Win2K/NT?
+
+Yes, it can run as a system service using srvany.exe. The only catch is that
+this will effectively disable the Privoxy icon in the taskbar. You can have one
+or the other, but not both at this time :(
+
+There is a pending feature request for this functionality. See thread: http://
+sourceforge.net/tracker/?func=detail&atid=361118&aid=485617&group_id=11118, for
+details, and a sample configuration.
+
+-------------------------------------------------------------------------------
+
+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.
+
+-------------------------------------------------------------------------------
+
+4. Miscellaneous
+
+4.1. How much does Privoxy slow my browsing down? This has to add extra time to
+browsing.
+
+It should not slow you down any in real terms, and may actually help speed
+things up since ads, banners and other junk are not being displayed. The actual
+processing time required by Privoxy itself for each page, is relatively small
+in the overall scheme of things, and happens very quickly. This is typically
+more than offset by time saved not downloading and rendering ad images.
+
+"Filtering" via the filterfile mechanism may cause a perceived slowdown, since
+the entire page is buffered before displaying. See below.
+
+-------------------------------------------------------------------------------
+
+4.2. I noticed considerable delays in page requests compared to the old
+Junkbuster. What's wrong?
+
+Using the default filtering configuration, I noticed considerable delays in
+page requests compared to the old Junkbuster. Loading pages with large contents
+seemed to take forever, then suddenly delivering all the content at once.
+
+The whole content must be loaded in order to filter, and nothing is is sent to
+the browser during this time. The loading time does not really change in real
+numbers, but the feeling is different, because most browsers are able to start
+rendering incomplete content, giving the user a feeling of "it works".
+
+To modify the content of a page (i.e. make frames resizeable again, etc.) and
+not just replace ads, Privoxy needs to download the entire page first, do its
+content magic and then send the page to the browser.
+
+-------------------------------------------------------------------------------
+
+4.3. What is the "http://p.p/"?
+
+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 and greater), you can get some
+information about Privoxy and change some settings by going to http://p.p/ or,
+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/ 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 are not running Privoxy, then http://p.p/ will fail, and http://
+config.privoxy.org/ will return a web page telling you you're not running
+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 2.9.13).
+
+-------------------------------------------------------------------------------
+
+4.4. Do you still maintain the blocklists?
+
+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?
+
+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 answers back to you.
+
+Fortunately there are many publicly usable anonymous proxies out there, which
+solve the problem by providing a further level of indirection between you and
+the web server, shared by many people and thus letting your requests "drown" in
+white noise of unrelated requests as far as user tracking is concerned.
+
+Most of them will, however, log your IP address and make it available to the
+authorities in case you abuse that anonymity for criminal purposes. In fact you
+can't even rule out that some of them only exist to *collect* information on
+(those suspicious) people with a more than average preference for privacy.
+
+You can find a list of anonymous public proxies at multiproxy.org and many more
+through Google.
+
+-------------------------------------------------------------------------------
+
+4.7. Can Privoxy guarantee I am anonymous?
+
+No. Your chances of remaining anonymous are greatly improved, but unless you
+are an expert on Internet security it would be safest to assume that everything
+you do on the Web can be traced back to you.
+
+Privoxy can remove various information about you, and allows you more freedom
+to decide which sites you can trust, and what details you want to reveal. But
+it's still possible that web sites can find out who you are. Here's one way
+this can happen.
+
+A few browsers disclose the user's email address in certain situations, such as
+when transferring a file by FTP. Privoxy does not filter FTP. If you need this
+feature, or are concerned about the mail handler of your browser disclosing
+your email address, you might consider products such as NSClean.
+
+Browsers available only as binaries could use non-standard headers to give out
+any information they can have access to: see the manufacturer's license
+agreement. It's impossible to anticipate and prevent every breach of privacy
+that might occur. The professionally paranoid prefer browsers available as
+source code, because anticipating their behavior is easier. Trust the source,
+Luke!
+
+-------------------------------------------------------------------------------
+
+4.8. Might some things break because header information is being altered?
+
+Definitely. More and more sites use HTTP header content to decide what to
+display and how to display it. There is many ways that this can be handled, so
+having hard and fast rules, is tricky.
+
+"USER AGENT" in particular is often used in this way to identify the browser,
+and adjust content accordingly. Changing this now is not recommended, since so
+many sites do look for this. You may get undesirable results by changing this.
+
+For instance, different browsers use different encodings of Russian and Czech
+characters, certain web servers convert pages on-the-fly according to the User
+Agent header. Giving a "User Agent" with the wrong operating system or browser
+manufacturer causes some sites in these languages to be garbled; Surfers to
+Eastern European sites should change it to something closer. And then some page
+access counters work by looking at the "REFERER" header; they may fail or break
+if unavailable. The weather maps of Intellicast have been blocked by their
+server when no "REFERER" or cookie is provided, is another example. There are
+many, many other ways things can go wrong when trying to fool a web server.
+
+If you have problems with a site, you will have to adjust your configuration
+accordingly. Cookies are probably the most likely adjustment that may be
+required, but by no means the only one.
+
+-------------------------------------------------------------------------------
+
+4.9. Can Privoxy act as a "caching" proxy to speed up web browsing?
+
+No, it does not have this ability at all. You want something like Squid for
+this. And, yes, before you ask, Privoxy can co-exist with other kinds of
+proxies like Squid.
+
+-------------------------------------------------------------------------------
+
+4.10. What about as a firewall? Can Privoxy protect me?
+
+Not in the way you mean, or in the way a true firewall can, or a proxy that has
+this specific capability. Privoxy can help protect your privacy, but not really
+protect you from intrusion attempts.
+
+-------------------------------------------------------------------------------
+
+4.11. The Privoxy logo that replaces ads is very blocky and ugly looking. Can't
+a better font be used?
+
+This is not a font problem. The logo is an image that is created by Privoxy on
+the fly. So as to not waste memory, the image is rather small. The blockiness
+comes when the image is scaled to fill a largish area. There is not much to be
+done about this, other than to use one of the other "imageblock" directives:
+pattern, blank, or a URL of your choosing.
+
+Given the above problem, we have decided to remove the logo option entirely [as
+of v2.9.13].
+
+-------------------------------------------------------------------------------
+
+4.12. I have large empty spaces now where ads used to be. Why?
+
+It would be easy enough to just eliminate this space altogether, rather than
+fill it with blank space. But, this would create problems with many pages that
+use the overall size of the ad to help organize the page layout and position
+the various components of the page where they were intended to be. It is best
+left this way.
+
+-------------------------------------------------------------------------------
+
+4.13. How can Privoxy filter Secure (HTTPS) URLs?
+
+This is a limitation since HTTPS transactions are encrypted SSL sessions
+between your browser and the secure site, and are meant to be reliably secure
+and private. This means that all cookies and HTTP header information are also
+encrypted from the time they leave your browser, to the site, and vice versa.
+Privoxy does not try to unencrypt this information, so it just passes through
+as is. Privoxy can still catch images and ads that are embedded in the SSL
+stream though.
+
+-------------------------------------------------------------------------------
+
+4.14. Privoxy runs as a "server". How secure is it? Do I need to take any
+special precautions?
+
+There are no known exploits that might effect Privoxy. On Unix-like systems,
+Privoxy can run as a non-privileged user, which is how we recommend it be run.
+Also, by default Privoxy only listens to requests from "localhost". The server
+aspect of Privoxy is not itself directly exposed to the Internet in this
+configuration. If you want to have Privoxy serve as a LAN proxy, this will have
+to be opened up to allow for LAN requests. In this case, we'd recommend you
+specify only the LAN gateway address, e.g. 192.168.1.1, in the main Privoxy
+config file. All LAN hosts can then use this as their proxy address in the
+browser proxy configuration. In this way, Privoxy will not listen on any
+external ports. Of course, a firewall is always good too. Better safe than
+sorry.
+
+-------------------------------------------------------------------------------
+
+4.15. How can I temporarily disable Privoxy?
+
+The easiest way is to access Privoxy with your browser by using the special
+URL: http://p.p/ and select "Toggle Privoxy on or off" from that page.
+
+-------------------------------------------------------------------------------
+
+4.16. Where can I find more information about Privoxy and related issues?
+
+Other references and sites of interest to Privoxy users:
+
+http://www.privoxy.org/, The Privoxy Home page.
+
+http://sourceforge.net/projects/ijbswa, the Project Page for Privoxy on
+Sourceforge.
+
+http://p.p/, access Privoxy from your browser. Alternately, http://
+config.privoxy.org may work in some situations where the first does not.
+
+http://p.p/, and select "actions file feedback system" to submit "misses" to

+
+5. Troubleshooting
+
+5.1. I just upgraded and am getting "connection refused" with every web page?
+
+Either Privoxy is not running, or your browser is configured for a different
+port than what Privoxy is using.
+
+The old Privoxy (and also Junkbuster) used port 8000 by default. This has been
+changed to port 8118 now, due to a conflict with NAS (Network Audio Service),
+which uses port 8000. If you haven't, you need to change your browser to the
+new port number, or alternately change Privoxy's "listen-address" setting in
+the config file used to start Privoxy.
+
+-------------------------------------------------------------------------------
+
+5.2. I just added a new rule, but the steenkin ad is still getting through.
+How?
+
+If the ad had been displayed before you added its URL, it will probably be held
+in the browser's cache for some time, so it will be displayed without the need
+for any request to the server, and Privoxy will not be in the picture. The best
+thing to do is try flushing the browser's caches. And then try again.
+
+If this doesn't help, you probably have an error in the rule you applied. Try
+pasting the full URL of the offending ad into http://config.privoxy.org/
+show-url-info and see if any actions match your new rule.
+
+-------------------------------------------------------------------------------
+
+5.3. One of my favorite sites does not work with Privoxy. What can I do?
+
+First verify that it is indeed a Privoxy problem, by disabling Privoxy
+filtering and blocking. Go to http://p.p/ and click on "Toggle Privoxy On or
+Off", then disable it. Now try that page again. It's probably a good idea to
+flush the browser cache as well.
+
+If still a problem, go to "Show which actions apply to a URL and why" from
+http://p.p/ and paste the full URL of the page in question into the prompt. See
+which actions are being applied to the URL. Now, armed with this information,
+go to "Edit the actions list". Here you should see various sections that have
+various Privoxy features disabled for specific sites. Most disabled "actions"
+will have a "-" (minus sign) in front of them. Some aliases are used just to
+disable other actions, e.g. "shop" and "fragile", and won't necessarily use a
+"+" or "-" sign. Add your problem page URL to one of these sections that looks
+like it is disabling the feature that is causing the problem. Rember to flush
+your browser's caches when making such changes! As a last resort, try "fragile"
+which disables most actions. Now re-try the page. There might be some trial and
+error involved. This is discussed in a little more detail in the user-manual
+appendix.
+
+Alternately, if you are comfortable with a text editor, you can accomplish the
+same thing by editing the appropriate "actions" file.
+
+-------------------------------------------------------------------------------
