Sep 27, 2016 · Even if you use Privacy Badger and other privacy-protecting add-ons, you can still possibly be tracked through a technique called “browser fingerprinting”. Panopticlick investigates how unique each browser is—and shows users just how easy it is for third parties to uniquely identify their browsers. Browser fingerprinting is an extremely subtle and problematic method of tracking, which we documented with the Panopticlick project. Privacy Badger can detect canvas based fingerprinting, and will block third party domains that use it.

The Firefox equivalent doesn't seem to work. Here is an example of what the Chrome extension blocks.
