Facebook Popups in lower left-hand screen of MacBook Pro OS Sierra
I can not get the pop-up notifications on Facebook to turn off. They appear in the lower left-hand side of my screen. I have turned off all notifications for Facebook through Facebook as well as through safari. It is incredibly annoying and won't stop! I get a lot of notifications though Facebook! Is there a way to make it stop??! Every post tells me to go through Facebook and Safari and change the preference to "NONE" on notifications, I have done that! I have attached a picture of what I am seeing - its not the banner in the top right, those are off.
MacBook Pro (Retina, 13-inch, Mid 2014), macOS Sierra (10.12.2)
