This section will provide a quick summary of ad blocking so you can get up to speed quickly without having to read the more extensive - information provided below, though this is highly recommeneded.

First a bit of a warning ... blocking ads is much like blocking SPAM: the more aggressive you are about it, the more likely you are to block - things that were not intended. So there is a trade off here. If you want + things that were not intended. And the more likely that some things + may not work as intended. So there is a trade off here. If you want extreme ad free browsing, be prepared to deal with more "problem" sites, and to spend more time adjusting the configuration to solve these unintended consequences. In short, there is - not an easy way to eliminate all ads. Either take - the easy way and settle for most ads blocked with the default configuration, or jump in and tweak it for your personal surfing habits and preferences.

An ad image for instance, is just a URL + original page's HTML content. An ad image for instance, is just an URL embedded in the page somewhere. The image itself may be on the same server, or a server somewhere else on the Internet. Complex web pages will have many - such embedded URLs.

Privoxy can deal with each URL individually, so, for + instance, the main page text is not touched, but images from such-and-such + server are blocked.
