Firefox 74 lets you use Facebook, but encourages you to “isolate” it to prevent the social network from monitoring everything you do
The Firefox web browser’s obsession with privacy It is well known: it is one of its great arguments to convince users of its advantages over other alternatives -especially Chrome-, and in its latest version it has once again offered new options in this regard.
One of the most notable is how to treat Facebook in the new Firefox 74. You can use that social network from the browser, of course, but Firefox encourages you to use an extension called Facebook Container that “encloses” that session in a kind of confinement cell. The objective is none other than isolating Facebook so that it is not able to monitor everything that happens in the browser beyond what you do in the service.
If you want to use Facebook in Firefox, you still want to protect your privacy a bit first.
The new version of Mozilla’s browser appeared a few days ago. If you have updated to Firefox 74 You may have come across a new informational tab that you may have closed without paying too much attention, but that showed a unique message.
In it, the people in charge of Mozilla and Firefox indicated that “if you more or less like Facebook but don’t trust them, try the Facebook Container extension for Firefox and make it more difficult for them to monitor you in your web browsing“.
The description of this Firefox add-on or extension is clear as well. Through her it is possible to isolate the Facebook identity in a separate container so that the social network cannot follow your steps through third-party cookies.
When installing and activating it we will see how when we access Facebook for the first time Firefox will have expelled us from the open session if we had it. This deletes the Facebook cookies and forces us to log in again, but this time in the container created to isolate that particular tab.
The “Share on Facebook” links from other web pages will also be loaded into tabs with Facebook Container, and the built-in Facebook comments and “Like” buttons will not work on other tabs outside of the container, something that prevents Facebook from associating information about your activity on other web pages with your identity on the social network.
The extension now available in its version 2.1.0 has gained integers and allows add a custom list of sites to open in the container so you can “log in with Facebook when you need it”. So if you use your Facebook account to identify yourself on a website or web service, you can add it to the list to avoid problems.
The option is therefore one more guarantee of privacy protection that joins the rest of the improvements implemented in this regard in Firefox 74. The removal of support for TLS 1.0 / 1.1 is for example important also because it is a protocol that is 20 years old and stopped being recommended a decade ago.
