Firefox 85 removes support for Flash and adds protection against supercookies

Mozilla has released Firefox 85 ending support for Adobe Flash Player plugin and has brought in ways to block supercookies to enhance a user’s privacy. Mozilla, in a blog post, noted that supercookies are store user identifiers, and are much more difficult to delete and block. It further noted that the changes it is making through network partitioning in Firefox 85 will “reduce the effectiveness of cache-based supercookies by eliminating a tracker’s ability to use them across websites.”

“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,” Mozilla noted.

It explained that the network partitioning works by splitting the Firefox browser cache on a per-website basis, a technical solution that prevents websites from tracking users as they move across the web. Mozilla also noted that by removing support for Flash, there was not much impact on the page load time. The development was first reported by ZDNet.
