I have a problem with facebook.com, and scrolling at this site. With my add-ons from firefox, when I scrolling facebook.com, my lenovo ideapad have black. Then I must restart system. Today try scrolling facebook on microsoft edge, and I don't have any problems. Then I try with my firefox, without any add-ons, and problem fixed.
