I am being blocked by Firefox from BT sign in, Google, Yahoo, Duckduckgo and my own office Citrix sign in. Firefox will not allow me to make any exceptions

the message given on each occasion is along these lines:-

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.

Thank you for your reply. I wasn't able to find anything in Kaspersky which covered this, but did find advice to delete cert8, which solved the problem
