Firefox 85 Cracks Down on Supercookies

Trackers and adtech companies have long abused browser features to follow people around the web. Since 2018, we have been dedicated to reducing the number of ways our users can be tracked. As a first line of defense, we’ve blocked cookies from known trackers and scripts from known fingerprinting companies.

In Firefox 85, we’re introducing a fundamental change in the browser’s network architecture to make all of our users safer: we now partition network connections and caches by the website being visited. Trackers can abuse caches to create supercookies and can use connection identifiers to track users. But by isolating caches and network connections to the website they were created on, we make them useless for cross-site tracking.
