"Prevent Facebook from tracking you around the web. The Facebook Container extension for Firefox helps you take control and isolate your web activity from Facebook.
Facebook Container also deletes Facebook cookies from your other containers on install and when you restart the browser, to clean up any potential Facebook trackers.
Not on FB these days? It works with Instagram, FB Messenger and Workplace, too."
I guess I'm on a mozilla mailing list. Never used FB myself.
