With the Mozilla Firefox ADD-ONS extension “Facebook Container,” you can avoid Internet monitoring over the site.
Firefox’s Facebook Container Extension lets you take control of Facebook and separate your web operation. Use Firefox 57 and higher to run this plugin on Windows.
Facebook Container works by isolating your Facebook identity into a separate container which makes it more difficult for Facebook to monitor your visits to other third-party websites with cookies. Installing this extension closes your Facebook tabs, deletes your Facebook cookies, and signs off Facebook. The next time you post to Facebook it will load into a new window colored blue tab (the “Container”).
When on Facebook Box, you will usually sign in and use Facebook. Clicking on a non-Facebook link or navigating to a non-Facebook website in the URL bar will load certain pages outside the folder.
Clicking Facebook Sharing buttons will load them within the Facebook container on other browser tabs. You should be mindful that using these buttons transfers information about the website you shared from Facebook. Some features don’t work, you’ll only be logged in to Facebook in the Container, Facebook comments embedded, and like buttons in tabs outside of the Facebook, Container won’t function. This prohibits Facebook from linking information about your actions to your Facebook identity on websites outside of Facebook.
Furthermore, websites that require you to build an account or log in using your Facebook credentials do not function properly in general. Since this extension is intended to isolate Facebook use from using other websites, it is expected that this behavior. Facebook Container also deletes Facebook cookies on launch from your other containers and cleans any possible Facebook trackers when you restart the browser. Multi-account bins aren’t doing this for you.
