Difficult to troubleshoot
Privoxy is a free, open-source local proxy for blocking ads and tracking scripts.
Ad blocking is a controversial subject; much of the content you consume on the Web every day is made possible only thanks to ad revenue–and if everyone blocked ads, websites may have to use other means to generate revenue, such as putting their content behind a paywall. That said, some people feel that ads are not only irritating, but also violate their privacy. If you are of these people, Privoxy is a free tool that offers a wealth of ways to rid yourself of ads and tracking.
There are many browser-specific add-ons for blocking ads, such as the excellent Adblock Plus for Firefox and Chrome. But these run within the browser, and may crash or make it slower. Privoxy runs outside the browser, and is browser-agnostic: All browsers on your system can use this single tool and surf ad-free, even if they don’t have ad-blocking plugins of their own.
If you are just looking to block ads, Privoxy is simple enough to use: Just install it, tell your browser to use it as a proxy (this changes from browser to browser), and you’re done. I didn’t tweak any configuration options, and ads all but disappeared from the websites I tested. I did notice a couple of quirks, such as images not loading on a test website, but when I tried the same website in a different browser it worked fine (and then it started working in the first browser too).
While Privoxy’s default configuration is robust enough, if you feel the need to troubleshoot or modify anything, you’d best set aside an hour or two to dig through the extensive documentation and lengthy configuration files. Privoxy provides a built-in troubleshooting tool to help you understand why it blocked (or didn’t block) a certain URL, but its output can be cryptic and is a far cry from intuitive browser tools that let you eliminate ads just by clicking on them. Privoxy’s FAQ claims that “complicated is in the eye of the beholder”–well, this beholder sure feels it’s complicated.
Privoxy’s documentation shows how passionate the authors are about ad blocking and privacy protection on the Web: I don’t remember the last time I’ve read a manual that referred to a software product as “a veritable arsenal of tools with which to exert our control, preferences and independence.”
Whether or not Privoxy’s immense power is worth the hassle of configuring it is up to you–just like deciding if you want to use an ad blocker in the first place.
