All the website i used to visit are now (version 65) blocked by Firefox. Exemple trying to reach my Google account :

The owner of calendar.google.com has configured their web site improperly. To protect your information from being stolen, Firefox has not connected to this web site. This site uses HTTP Strict Transport Security (HSTS) to specify that Firefox only connect to it securely. As a result, it is not possible to add an exception for this certificate.

I can access this account and all the rest with Chrome and with IExplorer

Please help. I want to continue with Firefox

There is security software like Avast, Kaspersky, BitDefender and ESET that intercept secure connection certificates and send their own.

Effectively, my problem is solved. Thanks. I am happy I can continue with Firefox (although it cost me 3 hours...)
