I am writing this at the library which limits me somewhat as I cannot open certain web pages. This morning I turned my computer on, turned the 3 wifi which is connected to it on, and the screen acted as normal until I clicked on the Firefox symbol which usually takes me to Google sign in... but I got a message up which said that it was not a safe connection as the certificate had expired in the connection that had come up, and it had probably been compromised by third party ....... or words to that effect. No matter how I tried to log on, it would not let me. The wifi was ok it was connected and found .... I cannot obviously get onto the internet to gon onto another browser etc.... Can anyone suggest anything please? Please remember I am in the library so if I don't come back for a few days that is why but if I am still here logged in I will receive your answer. Thank you.
