Recently my login page for facebook in firefox has changed. The exact same url (facebook.com) in all other browsers I have (Chrome, Brave, IE, and Edge) renders a different page. I've been using facebook container plugin for quite a while but never experienced this other login page format. I disabled the facebook container plugin but still get the same result with it disabled. I typically have private mode set by default. I cleared my cache. I'm trying to think of all of the constraints that might affect this. If it's a result of my privacy settings and this isn't atypical, then I would like to know. Otherwise, I'm puzzled by the difference. Thanks for your time!
