Mozilla says that all Firefox users will now be protected by default against cross-site tracking while browsing the Internet.
"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."
Today's announcement further highlights Mozilla's ongoing fight against ad tech companies' online tracking efforts that started in 2018 when it first introduced the Enhanced Tracking Protection feature.
One year later, Mozilla toggled on Enhanced Tracking Protection in Firefox by default to automatically block cookies from known trackers.
After the launch of Firefox 72 in January 2020, Mozilla's web browser also started auto-blocking scripts used by fingerprinting companies for browser fingerprinting via cross-site tracking.
With the rollout of Total Cookie Protection, Mozilla now protects more than 211 million monthly active users and 3,26% of the browser market share worldwide from cross-site tracking attempts.
