Problems with connectivity when Firefox says "Secure Connection Failed"

Today I got the Firefox message "Secure Connection Failed" when I composed and tried to send Yahoo email to a friend who I have corresponded with for several years. In addition, a few months ago I could not connect on a Televisit with my doctor when I clicked the link her office sent. Again I got the Firefox message "Secure Connection Failed."
