There are several possibilities:
+Privoxy is not running. + Solution: verify that Privoxy is + installed correctly, has not crashed, and is indeed running. Turn + on Privoxy's logging, and look at + the logs to see what they say.
+Or your browser is configured for a different port than what + Privoxy is using. Solution: verify + that Privoxy and your browser are + set to the same port (listen-address).
+Or if using a forwarding rule, you have a configuration problem + or a problem with a host in the forwarding chain. Solution: + temporarily alter your configuration and take the forwarders out of + the equation.
+Or you have a firewall that is interfering and blocking you. + Solution: try disabling or removing the firewall as a simple + test.
+- There are several possibilities: -
-- Privoxy is not running. - Solution: verify that Privoxy - is installed correctly, has not crashed, and is indeed running. - Turn on Privoxy's logging, and - look at the logs to see what they say. -
-- Or your browser is configured for a different port than what - Privoxy is using. Solution: - verify that Privoxy and your - browser are set to the same port (listen-address). -
-- Or if using a forwarding rule, you have a configuration problem - or a problem with a host in the forwarding chain. Solution: - temporarily alter your configuration and take the forwarders - out of the equation. -
-- Or you have a firewall that is interfering and blocking you. - Solution: try disabling or removing the firewall as a simple - test. -
-- More than likely this is a problem with your TCP/IP networking. - ZoneAlarm has been reported to cause this symptom -- even if not - running! The solution is to either fight the ZA configuration, or - uninstall ZoneAlarm, and then find something better behaved in its - place. Other personal firewall type products may cause similar type - problems if not configured correctly. -
-- 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 involved. - Flush 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 it - really matches your new rule. Blocking ads is like blocking spam: a - lot of tinkering is required to stay ahead of the game. And - remember you need to block the URL of the ad in question, which may - be entirely different from the site URL itself. Most ads are hosted - on different servers than the main site itself. If you right-click - on the ad, you should be able to get all the relevant information - you need. Alternately, you can find the correct URL by looking at - Privoxy's logs (you may need to - enable logging in the main config file if its disabled). -
-- Below is a slightly modified real-life log snippet that originates - with one requested URL: www.example.com - (name of site was changed for this example, the number of requests - is real). You can see in this the complexity of what goes into - making up this one "page". There are - eight different domains involved here, with thirty two separate - URLs requested in all, making up all manner of images, Shockwave - Flash, JavaScript, CSS stylesheets, scripts, and other related - content. Some of this content is obviously "good" or "bad", but not - all. Many of the more questionable looking requests, are going to - outside domains that seem to be identifying themselves with - suspicious looking names, making our job a little easier. Privoxy has "crunched" (meaning caught and BLOCKED) quite a few - items in this example, but perhaps missed a few as well. -
