Hi people I am a loyal Firefox customer for 10 years. I have a Windows 10 Pro 64 bit laptop and for security am using Bitdefender total internet security 2018. This is the error message I am getting on EVERY page! "Your internet is not secure The owner of (any site) .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."

I have checked the fire wall and Firefox is permitted, I have turned off Bitdefender entirely to no avail. I have the latest Firefox version Edge works fine but until two days ago, so did Firefox.
