Mozilla is planning to release a series of features in the coming months so as to offer more vividness and controls to the users. One of the major decisions includes the ad-tracking blocker so as to bring an easy environment for the users which could even be customizable when in need. This means soon enough, Firefox browser will start blocking ad trackers so that you won’t require any third-party extension for the same.

Mozilla in its blog post explains that the ad trackers not only compromise security but also put a negative impact on the performance which isn’t good for a browser. Mozilla cites the data by Ghostery in explaining the fact that tracking slows down the web. According to the data, "55.4% of the total time required to load an average website was spent loading third-party trackers. And, the slow speed frustrates even more when a user is on the slower network."

According to Mozilla, the blocker for ad trackers has already been added to its Nightly build. This means, Mozilla is currently testing it and if everything goes well, Firefox will start blocking slow-loading trackers by default. And, this change would come via the Firefox 63 version in the near future.

Another change that is expected to come soon is the blocking of storage access from the third-party tracking content. Mozilla shows its concerns towards the privacy of the users which may hinder when the ad trackers spy on them. Mozilla says that a number of vendors follow the users on the internet, spying on the products they are purchasing or looking to purchase. So, for this reason, Firefox will strip cookies and block storage access from third-party tracking content. This is already available in the Nightly build and after the testing, it will arrive via the version 65 of the browser.

Another privacy thing that makes the “web a more hostile place to be” is a bad practice of tracking users’ activities. Things like fingerprint tracking aren’t in the hands of users and thus browsers should take a strong grip on them.

Mozilla writes,

This is about more than protecting users — it’s about giving them a voice. Some sites will continue to want user data in exchange for content, but now they will have to ask for it, a positive change for people who up until now had no idea of the value exchange they were asked to make.
