The Mozilla Foundation has released its latest version of the Firefox browser, which comes with new privacy protections to squash cross-site cookie tracking, as well as a slew of security vulnerability fixes.

"Total Cookie Protection confines cookies to the site where they were created, which prevents tracking companies from using these cookies to track your browsing from site to site," said Tim Huang, Johann Hofmann and Arthur Edelstein with Mozilla on Tuesday.

Total Cookie Protection aims to reign in some of these privacy concerns by creating what Mozilla calls a separate "Cookie jar" for each website that a user visits.

"Only when Total Cookie Protection detects that you intend to use a provider, will it give that provider permission to use a cross-site cookie specifically for the site you're currently visiting," said Huang, Hofman and Edelstein.

Mozilla has been on a war path against tracking cookies since 2018, when it announced a campaign blocking tracking cookies by default in Firefox and implementing various other privacy measures in its browser.

In October 2018, for stance, Firefox rolled out enhanced tracking protection features, which gave users the option to block cookies and storage access from third-party trackers.
