MacBook Pro acting strange after a power surge. The date and time gone back to 2000 and when I tried to connect to the internet I had to join network and type in my password. Any site I go to Firefox say your connection is not secure The owner of Google.com has configured their website inproperly. To protect your information from being stolen, Firefox has not connected to this website. This site uses http strict transport security HSTS to specify that Firefox only connects to it security. As a result it is not passable to add an exception for this certificate. If I try to go on the Internet with safari it say Safari can't verify the identity of the website www.yahoo.com The certificate to the website is invalid. You might be connecting to a website that is pretending to be www.yahoo.con What do you think could be going on.
