Total Cookie Protection, Mozilla’s most potent cookie-blocking technology to date, will soon be available for the Firefox browser.
By blocking third-party cookie trackers, the new technology prevents advertising from following visitors from one website to another.
All cookies are restricted by the new Firefox cookie blocker to a “cookie jar” that belongs only to the website that set the cookie. When a person leaves one website and visits another, all cookies that were previously placed by that website are effectively disabled.
“Total Cookie Protection works by creating a separate “cookie jar” for each website you visit. Instead of allowing trackers to link up your behavior on multiple sites, they just get to see behavior 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.
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.” Firefox said.
Total Cookie Protection is now available as a default feature in Firefox for Desktop. This means that users do not have to dig through the browser settings to enable it, it is enabled by default. This strategy keeps websites operating while enabling analytics data collection that can improve the user experience for visitors.
The feature is also available through the Firefox Private browsing experience and in Mozilla’s dedicated privacy browser for mobile devices, Focus. The Focus browser is compatible with both Android and iOS devices.
