While these features are nice, Firefox 86 also brings total cookie protection, and that’s very important for your privacy.

Mozilla introduced Enhanced Tracking Protection in 2019 to block malicious cookies from clients. Last month it rolled out protection measures from Supercookies — a type of cookies that are hard to track and delete. You can download Firefox 86 from here.
