![]() ![]() ![]() A benchmark run on a well-primed Privacy Badger should have significantly lower numbers. Privacy Badger is run on a fresh installation, and does not block nearly 3rd-party requests as the commercial extensions, but that’s by design. His methodology is to visit 15 well-trafficked sites several times, and average the number of requests that slip through.Īs you can see, the Ghostery and Adblock numbers are very similar, with Disconnect trailing slightly behind. Developer Raymond Hill, who has been working on a excellent privacy-oriented developer extension called HTTP Switchboard, is able to run what he calls a “ browser session benchmark,” checking to see how many requests get past the various blockers. For the most part, all the blockers currently on the market do a pretty good job of blocking third-party requests. The difference between Privacy Badger and the other blocker extensions is not an issue of effectiveness. Out of the box, Privacy Badger won’t block nearly as many third-party requests as the commercial options, but as you use it more, it will learn more and more hosts to block, although it does come with a built-in whitelist for things like Google Maps and Paypal, which are needed to browse the web normally. The salient difference between Privacy Badger and the other extensions is that Privacy Badger’s blacklist is generated through heuristic blocking, which means it gets better the longer it is used. While Adblock and Adblock plus allow users to add upload their own blacklists and whitelists, Ghostery and Disconnect do not even allow users to add new filters. Adblock is donation-supported, but many users confuse it with Adblock Plus, which has generated controversy for having advertisers pay to land on a whitelist. Disconnect takes a pay-what-you-want approach, but it is still developed by a for-profit company founded by a former Google engineer. Ghostery makes money by tracking the trackers while blocking them and selling data about third party trackers, which it calls Ghostrank. Adblock claims it is the most downloaded extension on the Chrome Web Store, and both it and Adblock Plus have millions of downloads.įrom left to right: Privacy Badger, Disconnect, Adblock Pro, Adblock, HTTP Switchboard, Ghostery As you browse, if it detects the same third-party domain tracking you across three different sites, it blocks it.Īd blockers are widely downloaded. Privacy Badger’s blacklist is user-generated: instead of blocking sites, Privacy Badger blocks objectionable behaviors. Blockers download a list of bad domains from a remote location out of the box, which is the blacklist most users settle on. Previously, blockers have used a centralized blacklist approach. Privacy Badger is different from other blockers, however, and not just because it’s developed by a nonprofit. That’s what privacy wonks like to call a “third-party request,” and it’s what Privacy Badger seeks to block. For instance, if a blog has an embedded Facebook Like button, that widget makes it so you can easily like that page, but it’s also tracking your activity across the internet. When someone clicks on a site, they request information from domains that aren’t necessarily the site they asked to visit that’s just the way hypertext - the “HT” in “HTTP” - works. Privacy Badger, an extension for Firefox and Chrome, disallows cookies from certain third-party domains. There wasn’t a real enforcement mechanism - until the Electronic Frontier Frontier released Privacy Badger, which lets users opt out of tracking across the internet. But the standard was poorly adopted because many of the biggest advertising companies on the internet aren’t crazy about such an idea. In fact, in 2009, a group wrote a standard so that web browsers could do just that. ![]() It would be great if internet users could tell the websites they visit that they don’t want to be tracked by advertising groups unrelated to the webpage they’re viewing.
