Firefox SEC_UNKNOWN_ISSUER Problem Firefox Your Connection Is Not Secure Problem.

The error code SEC_ERROR_UNKNOWN_ISSUER is meant to tell users that a website is attempting to use an SSL certificate that was issued by an untrusted entity. The way public key infrastructure (PKI) works — and in order for it to function correctly — only trusted certificate authorities (CAs) can issue trusted certificates. There’s a very strict set of guidelines that CAs follow to ensure that they’re both performing their due diligence concerning validation and that they’re acting in good faith when they issue certificates. Any mistakes are dealt with harshly, so there’s plenty of incentive to get things right.

The warning refers to the lack of security for the connection to that page. It’s alerting you that information sent and received with that page is unprotected and it could potentially be stolen, read, or modified by attackers, hackers, and entities with access to internet infrastructure, such as Internet Service Providers (ISPs) and governments.

This “Not Secure” warning appears on all pages using the HTTP protocol, which is incapable of providing a secure connection. Historically, this has been the primary protocol used for internet communication.

Over the last few years, websites have been transitioning to HTTPS—note the S appended to the end—which does provide security and is used by millions of websites including Google.com, Facebook.com, and Amazon.com, to protect your information while browsing, logging in, and making purchases.

The “Not Secure” warning does not indicate that your computer or the site you are visiting is affected by malware. It only serves to alert you that you do not have a secure connection with that page. Note that some websites may only support secure HTTPS connections on some pages, but not all; in these cases you may see the “Not Secure” warning on only the insecure pages.
