Among the advertisements displayed on many websites are "behavior tracking" function which grasps what kind of site the user is browsing the page and what kind of action is taken There are many things that have. Although it is unlikely that the action and the specific individual are actually linked, it has been pointed out that this tracking function becomes a very serious obstacle in realizing free and privacy browsing .

"In the physical world, consumers think that a number of merchants monitor 1 to 10 actions related to their shopping, they know what products they saw, what they bought, etc. "Nick Nguyen wrote in Mozilla's blog," Also, users expect similar privacy on the web, but in reality, everywhere they visit is monitored everywhere. " He states that the fact that many users are grasping actions by the tracking function is said.

In response to this situation Mozilla decided to introduce "anti-tracking" efforts. The blog tells us about improvement on the following three points.

◆ 1: Reduce page loading time <br> Tracking caused the adverse effect that the loading time of the page contents becomes long, investigation by investigation company Ghostery is necessary to load the average website It is said that 55.4% of the total time spent is spent reading third-party trackers. This trend is more pronounced in environments with slow network speed.

In order to deal with this problem, Mozilla added a function to block the tracker to "Firefox Nightly" which is the early development stage of each version, and in September 2019, a shield study targeting some beta users It is planned to be implemented. As development progresses, Firefox 63 implements anti-tracking functionality for all users.

◆ 2: Elimination of cross site tracking - As mentioned above, most users do not like their actions being tracked on the net. In order to achieve user privacy and free browsing, Firefox will change the cookies so that third-party tracking content will not be able to access the storage in the future.

We already implemented this change in Firefox Nightly, and we plan to implement a shield study from September 2018. And it is planned to be implemented in Firefox 65 official version scheduled to be released in January 2019.

◆ 3: Mitigate harmful practices - Fraudulent acts of collecting identifiable user information invisibly and lowering user experience are becoming commonplace. For example, some trackers allow users to identify users invisibly in their device properties, but they can not control it. In another site, an encryption script which sees the encrypted communication on the user's device without knowing it is introduced. Such behavior is not favorable for free web. In future versions of Firefox, these methods will be blocked by default.

If you are interested in these functions, you can also try using Firefox Nightly which is distributed by the following link. However, since it is not an official version, please pay attention to the possibility that unknown bugs are included.
