Even if Facebook is containerized, if you make a purchase on <site>.com they might just tell Facebook (without the browser involved)

  Apparently this can be done in a brick-and-mortar (Home Depot, Pavillions, so on) too. And I mean even without ID, members card, ewallet, etc... There's nothing Mozilla can do about that too.

  But that site would have to know what your Facebook profile is. And with FB domains blocked outside of the FB container, they're going to have a harder time putting that info together.

    Could they just use your email address?

        That helps only for breaches involving specific email addresses. What the GP is hinting at is Facebook having your email address and you using the same email address on a site for a purchase. Sellers usually upload their customers' email addresses on to Facebook and other social media platforms so that they can target these users better. So if you use the same email address everywhere, then linking all your interactions and transactions is a certainty.

I didn't find a lot of activity here (most was wrong), but Albertsons and Home Depot had hits. I've never given either my Facebook info. https://facebook.com/off_facebook_activity/ https://facebook.com/off_facebook_activity/
