Mozilla Firefox 86 was released today with Total Cookie Protection, a new privacy feature that prevents web trackers from keeping tabs on your activity while browsing the web.
Windows, Mac, and Linux desktop users can upgrade to Firefox 86 from Options -> Help -> About Firefox. Firefox will automatically check for the new update and will install it if available.
Total Cookie Protection, works by maintaining a separate “cookie jar” for each website you visit. Any time a website, or third-party content embedded in a website, deposits a cookie in your browser, that cookie is confined to the cookie jar assigned to that website, such that it is not allowed to be shared with any other website.
