Firefox gets next-gen anti-tracking defense, stymies 'bounce' trackers
Mozilla today announced a new defense against advanced tracking tactics that it will be switching on in Firefox 79 starting immediately and pushing out to the remaining user base during the next few weeks.
Calling the improved technologies and techniques Enhanced Tracking Protection 2.0 – Mozilla said that ETP 2.0's primary job is to block redirect tracking, also known as bounce tracking.
Trackers have been exploiting a loophole of sorts to continue following users browsing with Firefox, which enabled its first-generation ETP by default in June 2019. ETP takes a hands-off approach for first-party cookies – those tied to the site being browsed – because to do otherwise would break many of those websites or require users to, say, log in each time they returned.
