I already start the activation of ETP 2.0 in Firefox

Mozilla recently released through an advertisement your intention to enable Enhanced Tracking Protection (ETP 2.0), as eLast year they enabled ETP by default on Firefox because they believe that understanding the complexities and sophistication of the ad tracking industry shouldn't be necessary to stay safe online.

ETP 1.0 was the first important step to fulfill that commitment to users. Since they enabled ETP by default, they have blocked 3,4 trillion tracking cookies.

Now with the evolution of ETP 2.0 the main innovation is the addition of Redirect tracking protection.

And it is that since the introduction of ETP, ad industry technology has found other ways to track users: creating solutions and new ways to collect your data to identify you while browsing the web.

Redirect tracking follows Firefox's built-in third-party cookie blocking policy when passing through the crawler's site before landing on the desired website. This allows them to see where you are coming from and where you are going.

Firefox has allowed users to see a report on blocked trackers since version 70, specifically the number of site and social media trackers, fingerprints, and crypto-mining. Information about trackers on a page can be accessed directly via the sign symbol in the address line. Fingerprint scripts are also blocked by default.

To avoid blocking cookies by third-party components loaded in the context of the current page, ad networks, social networks and search engines, when clicking on the links, started redirecting the user to an intermediate page, from which they then forward to the destination site.

Since the intermediate page opens on its own, outside the context of another site, tracking cookies can be installed on that page without hindrance.

To combat this method, ETP 2.0 has added blocking on the list of domains provided by the Disconnect.me service They use tracking through redirects.

With ETP 2.0, Firefox users will now be protected against these methods, as it checks to see if cookies and site data from those trackers need to be removed every day. ETP 2.0 prevents known trackers from accessing your information, even those with whom you may have inadvertently visited. ETP 2.0 clears cookies and site data from tracking sites every 24 hours.

For sites that do this type of tracking, Firefox will erase cookies and data on internal storage (localStorage, IndexedDB, Cache API, etc.) on a daily basis.

As this behavior can lead to the loss of authentication cookies on sites whose domains are used not only for tracking but also for authentication, an exception has been added.

If the user explicitly interacted with the site (for example, you scrolled through the content), the cookie will be deleted not once a day, but every 45 days, which, for example, may require re-entering Google or Facebook services every 45 days.

You can use the "privacy.purge_trackers.enabled" parameter to manually disable automatic cookie cleaning in about: config.

ETP 2.0 support was originally added in Firefox 79 but was disabled by default. In the coming weeks, it is planned to bring this mechanism to all categories of users.

Also, Google intends to allow blocking of inappropriate ads that are displayed when watching videos today.

If Google does not cancel the previously established deadlines, the following types of ads will be blocked in Chrome:

• Ads of any length that interrupt the video in the middle of the display.
• Long ad inserts (more than 31 seconds) are shown before the start of the video, without the ability to skip them 5 seconds after the start of the ad.
• Show large text ads or promotional images over the video if more than 20% of the video overlaps or if they appear in the middle of the window (in the middle third of the window).
