Redirect tracking is a technique that exploits cross-site navigation and is called ``temporarily redirecting users to another website'' so that trackers can use first-party cookies to track users across websites. The technique.

For example, if you search for 'the best running shoes' on the search engine, you will read the reviews etc. on the review site displayed in the search results, eventually move to the online store and purchase your favorite running shoes. Previously, each website displayed as a search result could use cookies to collect information about everyone who visited the page. However, Firefox introduced ETP to protect user privacy and blocked third-party cookies.

To counter this, redirect tracking has been devised to avoid techniques that block third-party cookies. For example, instead of going directly from the review site to the online store, by first going to the redirect tracker instead of the online site, the tracker will be able to read the first-party cookie, avoiding blocking third-party cookies and keeping it as usual. Will be able to track.

ETP 2.0, released by Firefox this time, will be able to protect users from this redirect tracking. The previous version of ETP 1.0 was also introduced in Firefox to prevent tracking, and Firefox enabled ETP 1.0 by default, resulting in the blocking of 3.4 trillion tracker cookies. However, ETP 2.0 can also prevent redirect tracking, which is a more sophisticated tracking technology, which helps protect users from more trackers.

ETP 2.0 blocks redirect trackers from accessing your information and removes cookies and site data from tracking sites every 24 hours. However, cookies are also used by search engines and social networks, so if cookies are deleted every day, you will be logged out every day from frequently used services such as email services and SNS. Therefore, Firefox does not delete cookies from sites that have been exchanged for the past 45 days, preventing accidental logouts from frequently used sites and preventing tracking without losing the benefits of cookies. It is possible.

It has been pointed out that various advertising systems have already switched to tracking using other than cookies. However, there are more and more add-ons that can bypass these new kinds of tracking.
