Today Firefox is introducing Enhanced Tracking Protection ETP 2.0 our next step in continuing to provide a safe and private experience for our users. ETP 2.0 protects you from an advanced tracking technique called redirect tracking also known as bounce tracking. We will be rolling out ETP 2.0 over the next couple of weeks.
Last year we enabled ETP by default in Firefox because we believe that understanding the complexities and sophistication of the ad tracking industry should not be required to be safe online. ETP 1.0 was our first major step in fulfilling that commitment to users. Since we enabled ETP by default weve blocked 3.4 trillion tracking cookies. With ETP 2.0 Firefox brings an additional level of privacy protection to the browser.
Since the introduction of ETP ad industry technology has found other ways to track users creating workarounds and new ways to collect your data in order to identify you as you browse the web. Redirect tracking goes around Firefoxs built-in third-party cookie-blocking policy by passing you through the trackers site before landing on your desired website. This enables them to see where you came from and where you are going.
