How does Facebook Container work?
The Facebook "Like" and "Share" buttons that appear on shopping, news and other sites contain Facebook trackers. Even if you don’t use them, Facebook uses these buttons to track you. Facebook Container blocks these trackers and will display a fence icon to show you where these trackers were removed.
When you visit Facebook, the add-on loads it in another tab and the fence icon is displayed in your address bar. This puts Facebook in its own boundary with other Facebook-owned sites, including Instagram and Messenger. You can allow other sites into the Facebook Container boundary, but this will allow Facebook to track more of your web activity.
When you visit a non-Facebook site that has Facebook trackers, Facebook Container will alert you and block these trackers.
You can add a website to Facebook Container if you prefer to allow Facebook to see your activity on that site.
How do I install Facebook Container?

Firefox will automatically switch to the Facebook Container tab for you. If you click on a link to a page outside of Facebook or type in another website in the address bar, Firefox will load them outside the Facebook Container. If a website has Facebook trackers, Facebook Container will block them and alert you.
What happens when I log in to other sites using my Facebook account?
Facebook login buttons on other sites contain Facebook trackers. You can still log in, but this will allow Facebook to track your activity there. Each site you allow into the Facebook Container allows Facebook to build a more complete snapshot of your online activity.

Will this protect me from Facebook completely?
This add-on does not prevent Facebook from mishandling any personal data it has already obtained or permitted others to obtain. Facebook will still have access to all your activity on facebook.com and the Facebook app, as well as any Facebook-owned applications such as Instagram and Messenger. This activity includes your comments, photo uploads, likes and any data you share with Facebook connected apps.
Other ad networks may try to link your Facebook activity with your regular browsing. In addition to using this add-on, there are other things you can do to maximize your protection, including changing your Facebook settings, using Private Browsing and Tracking Protection, blocking third-party cookies and/or using the Firefox Multi-Account Containers extension to further limit tracking.
