Suddenly, I cannot access any page with "google.com" in the address. The message is "Secure Connection Failed." Using Firefox 41.0 No problem on PC.
Problem started suddenly midday while working on an unrelated website. No Google.com address can be accessed via Firefox or Safari. Using latest version of Firefox (41.0), installed about 3 days ago. Problem is only on my Mac running OSx 10.9.5. Problem is not seen with Firefox running on a PC linked through the same modem to the internet. No third party security software is installed on the Mac.

Did you try a reboot of the system?
