I’ve been looking for a reason to uninstall all comodo browsers and this is a good one. One minute I was actively using google, and immediately after Icedragon updated I cannot access Google because of the common Firefox error - The owner of www.google.com has configured their website improperly. To protect your information from being stolen, IceDragon has not connected to this website.
This site uses HTTP Strict Transport Security (HSTS) to specify that IceDragon may only connect to it securely. As a result, it is not possible to add an exception for this certificate.
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
