Last year, Mozilla introduced a new feature called Enhanced tracking protection (ETP), what aims to improve privacy and avoid activity tracking web attacking cookies.
Cookies, generally stored on the user's device in the form of small text files, allow website developers to store user data to facilitate navigation and enable certain functions.
With its ETP function, Mozilla blocks third-party cookies, that is, the cookies placed on the user's computer by the server of a domain independent from that of the visited site.
These cookies are generally used by advertisers to offer you targeted advertising thanks to the advertising profile.
Privacy concerns, such as the Cambridge Analytica scandal on Facebook, justify the development of such features.
Of course, controlling browser cookies doesn't fix everything, but it can help solve some of the privacy problem by preventing businesses from tracking you more easily from one website to another.
About the new version of Firefox 67.0.1
With the arrival of the new version of Firefox 67.0.1 will now enable the ETP function by default in all new installations to make it difficult for more than a thousand companies to track browser users when they browse the Internet.
This feature will be enabled by default for new users who install and download Firefox for the first time, Enhanced Tracking Protection is automatically enabled as part of the »Standard« browser settings and blocks »third-party tracking cookies.
While For existing users, enhanced protection against default tracking will roll out in the coming months. But if you can't wait, you can activate it manually.
Since you can still disable this feature or simply disable blocking of a specific site, as this can cause some sites to not work properly.
Although you can also choose the different levels of blocking. Mozilla allows users to choose from different standard, strict, and custom options to control their level of online tracking.
Facebook Container is updated
In addition to enabling Enhanced Tracking Protection by default, Mozilla has updated other privacy features.
This is the case with Facebook Container. Released in late March 2018 in response to the Cambridge Analytica scandal, this is a Firefox extension that aims to make it much harder for Facebook to follow you when you're not on their site.
This tool, as its name implies, isolates Facebook from the rest of your web browsing activity, which should prevent the social network from following the user to any part of the web.
Facebook Container is an implementation of tabs technology or contextual containers that Mozilla has been working on for several years and whose production was made earlier than expected in response to the increasing demand for tools which would help to better adjust the Confidentiality and security parameters.
Container tabs allow browsing under different identities with a reduced risk of tracking, by eliminating the exchange of personal data of the user between tabs of different «contexts».
With the arrival of this latest update from Mozilla to the web browser Firefox 67.0.1 allows Facebook Container, which has had more than two million downloads since its launch, stop Facebook from following you on other sites with built-in Facebook features like "Share" buttons. "Likes" that are implemented on millions of websites.
For example, When you're on a news site and reading an article, you often see the "Like" and "Share" buttons. on Facebook. The Facebook container will block these buttons and all connections to the Facebook servers, so that the social network cannot track your visits to these sites. This blocking makes it much more difficult for Facebook to create user profiles.
