Yesterday I installed FF 43.0 - 64bit. I did as clean install as I could, uninstalled old version, and deleted from HDD every "mozilla" and "firefox" directory I could find. Since then, I am unable to access next sites (I believe list is not complete): https://www.google.com/ https://www.facebook.com/ https://www.google.com/maps https://www.google.rs/?gws_rd=ssl
Error msg is alwaays the same: "You have asked Firefox to connect securely to www.google.com, but we can't confirm that your connection is secure. Normally, when you try to connect securely, sites will present trusted identification to prove that you are going to the right place. However, this site's identity can't be verified. What Should I Do? If you usually connect to this site without problems, this error could mean that someone is trying to impersonate the site, and you shouldn't continue. 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. Technical details: www.google.com uses an invalid security certificate. The certificate is not trusted because the issuer certificate is unknown. The server might not be sending the appropriate intermediate certificates. An additional root certificate may need to be imported. (Error code: sec_error_unknown_issuer)"
All other browsers can access all sites without problems.
