Firefox 85 faces supercookies with the network partition and cache

The new version will be focused on protecting users from connection-based tracking

The Firefox browser has introduced network and cache partitions to the network, a feature aimed at protecting users from connection-based tracking, capable of disabling supercookies.

The partitions represent a “fundamental change” in the network architecture of the browser, and allow to isolate the network connections and cache with the webs, normally used to load shared elements more quickly, since in this way tracking is prevented of users, even through supercookies.

As explained from Mozilla, crawlers can abuse caches to create supercookies, which replace normal cookies to store user identifiers, but are more difficult to delete and block.

The changes introduced in Firefox 85 are focused on reducing the presence of supercookies through the network and cache partitions, since they “make them useless for monitoring between sites”, Mozilla points out on its official blog.

Firefox 85 also introduces pooled connection partitions, prefetch, speculative, and TLS session identifiers, to protect users from connection-based tracking.
