Mozilla has recently announced some more improvements to its user privacy in Firefox – via isolation of caches and network connections. This is essentially letting it crackdown on supercookies.
The company noted that supercookies collect users’ internet browsing habits information, and thus, they are challenging to identify and block. It is not appreciated to follow users on the web. The trackers often store such cookies in ETags, Flash storage, and HSTS flags.
Mozilla mentioned, “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.”
