As of now, Mozilla is introducing complete cookie protection for all users in its Firefox browser by default. Full cookie protection is the strongest protection for Firefox privacy to date, as stated in a message. This prevents tracking companies from being able to use these cookies to track your surfing behavior from website to website.
According to Mozilla, with full cookie protection, a separate “cookie jar” is created for each website you visit. Instead of trackers being able to link their behavior on multiple websites, they only see the behavior on a single website.
If a website or a third-party content embedded in a website now stores a cookie in the Firefox browser, this cookie is limited to the cookie collection point. According to the blog entry, no other website can reach into a cookie jar that does not belong to it – and thus not find out what the cookies of the other website know about you.
The launch of full cookie protection was preceded by functional tests, first in the strict mode of enhanced protection against activity tracking and in the private browsing window, then in the Firefox Clear browser at the beginning of this year, Mozilla continues. Now it will become a standard feature for all users of the Firefox desktop version worldwide.
