The Electronic Frontier Foundation has brought its Privacy Badger anti-tracking extension to Safari on the Mac, extending a tool that until now was limited to Chrome, Edge and Firefox. MacRumors reported the launch on October 19, citing an EFF press release.
Privacy Badger is free. On Safari it requires version 26.5 or later and runs on macOS.
How it differs from Safari's built-in protections
The EFF describes Privacy Badger as a tool that blocks ad trackers following people from site to site. Rather than relying only on a fixed list, the group says the extension uses algorithmic methods to learn which hidden trackers are at work. It does not block ads as such unless those ads also track users, according to the EFF.
Safari already restricts how much information trackers can collect, but, as MacRumors summarizes the EFF's argument, it still lets many of them load. Privacy Badger instead stops those trackers from loading, which the EFF says also defeats techniques designed to get around Safari's own protections.
Extra features
According to the report, the extension can also block cookies and strip link-click tracking from outgoing links on Facebook and Google. MacRumors does not detail the installation steps and points readers to the Privacy Badger website for the download.
Why it matters
Safari's tracking prevention has long been one of Apple's privacy talking points, and third-party extensions have been part of the picture for Mac users who want stricter controls. The arrival of a widely known open tool from a digital-rights group gives Safari users another option without switching browsers.
The details here come from MacRumors' account of the EFF announcement; Apple has not commented in the report, and no pricing beyond the free offering was mentioned. Users interested in trying it should check the EFF's own page for the current requirements and installation instructions, since compatibility depends on running Safari 26.5 or newer.
