Prevent Facebook from looking at the history of the sites visited

Facebook is a real spy, now everyone has understood it, so much so that there are numerous protests around the world by influential personalities and even national governments.
Facebook makes money not only with advertising, but also with the collection of personal data and the profiling of users that it can sell to external companies.
Going on the practical one, it can be noticed, both in the right side of the home page, and in the middle of the various news published by the friends, his advertisement made of pages and posts on which it is recommended to make "like". You may notice that this advertising is personalized for each user, in the sense that the recommended pages and advertisements concern things that are presumed to interest us.

How does Facebook know what we are interested in "> Prevent Facebook from transferring data to external companies and applications
The easiest way to prevent this Facebook ability to look at what sites we visit is by using Firefox with Mozilla's Facebook Container extension .
This extension opens the Facebook site in a separate container, like in a sandbox, so as to remain separate from the other sites visited.
After installing this extension, Facebook cookies are deleted and the Facebook account is disconnected. By reopening the Facebook site, this opens in a new blue tab (also known as the "container tab"), which prevents Facebook from reading Firefox's history and stored cookies and tracking activity via third-party cookies. Also, since Facebook is logged into the Container tab, the embedded Facebook comments and Like buttons on websites will not work.
Another way to exclude Facebook from the web browser history is on the Digital Advertising Alliance website.
From this portal you can download cookies (see what cookies are) that tell advertising sites not to look at our history.
From the list you will then need to find Facebook, put a cross and then click on the Submit button.
To find out more about Facebook advertising, there is an information page on personalized ads.
On this page you can make sure that Facebook advertising is not personalized based on the sites we visited previously.
To do this, click on Ad settings and put NO on all the options. In this way you will protect part of your privacy from Facebook on the PC browser which, obviously, is not enough. We must also stop tracking Facebook on smartphones or tablets .
On iPhone and iPad you have to open the general settings and find the privacy section.
From that option you will find a switch to stop advertisements
On Android smartphones and tablets, instead, you need to open the Google Settings application, find ads and check the box that says " disable interest-based ads ".
Other ways to block Facebook are extensions to not be tracked online by sites by blocking the collection of personal data and methods to block the saving of the sites visited in the browser history.
It is understood that these options probably do not protect us from all Facebook data collection practices since they live for this and use techniques they don't talk about and are unknown to us. At least, however, those who care about privacy will be able to prevent Facebook from looking at its chronology of sites, which is no small thing.
