Link tracking using JavaScript

[nandedamana]

Privacy Badger being able to unwrap Facebook and Google redirect links is great. But what about link tracking implemented using JavaScript? I mean, what if a site tracks link activity using click event listeners and beacons? Has it been observed? Has it been handled already?

Hello!

Sites tend to use third-party analytics services such as Google Analytics. Privacy Badger should already know to block all common analytics services, as part of Privacy Badger's mission of stopping non-consensual third-party tracking.

We added some first-party anti-tracking measures specifically for Facebook and Google because of the size of those platforms. These are exceptional cases, however, as Privacy Badger's main focus is on stopping pervasive third-party tracking.

Privacy Badger doesn't yet specifically look for beacons when learning what should be blocked. We may add beacon detection in a future update (#2024). But again, common third-party analytics services should already be getting blocked because of Privacy Badger's existing tracking detection heuristics.

Let me know if you have any questions.
