Version 65.0 blocks ALL websites

Veröffentlicht

Firefox just did an automatic update to version 65.0 (Firefox Quantum, 32 bit) and ALL of my websites are blocked with the message, "Your connection is not secure".

This is what I get back when I try to access Google: "The owner of www.google.com has configured their website improperly. 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 may only connect to it securely. As a result, it is not possible to add an exception for this certificate.


Even your own website is stopped with this message: "The owner of qsurvey.mozilla.com has configured their website improperly. To protect your information from being stolen, Firefox has not connected to this website."

...and Firefox will NOT allow me to bypass this warning, making the browser useless. I'm using Chrome to send you this message.
