over last few days receive error message: "secure connection failed....authenticity of data could nor be verified. This message occurs with search engine, trusted sites (NY Times, optimum.net, VPN Unlimited). I have returned Firefox to default settings, installed most recent version of firefox, turned off VPN to no avail. Other browser (Chrome) works fine....Suggestions?
