Today Mozilla announced that Firefox is rolling out Total Cookie Protection by default to all Firefox users worldwide. Total Cookie Protection is Firefox’s strongest privacy protection to date, confining cookies to the site where they were created, thus preventing tracking companies from using these cookies to track your browsing from site to site.

What is Total Cookie Protection?

Total Cookie Protection offers strong protections against tracking without affecting your browsing experience.

Total Cookie Protection creates a separate cookie jar for each website you visit. 

Total Cookie Protection works by creating a separate “cookie jar” for each website you visit. Instead of allowing trackers to link up your behaviour on multiple sites, they just get to see behaviour on individual sites. 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 only that website. No other websites can reach into the cookie jars that don’t belong to them and find out what the other websites’ cookies know about you — giving you freedom from invasive ads and reducing the amount of information companies gather about you.

This approach strikes the balance between eliminating the worst privacy properties of third-party cookies – in particular the ability to track you – and allowing those cookies to fulfill their less invasive use cases (e.g. to provide accurate analytics). With Total Cookie Protection in Firefox, people can enjoy better privacy and have the great browsing experience they’ve come to expect.

The release of Total Cookie Protection is the result of experimentation and feature testing, first in ETP Strict Mode and Private Browsing windows, then in Firefox Focus earlier this year.

Mozilla says bringing Total Cookie Protection to all Firefox users is their next step towards creating a better internet where your privacy is not optional.
