Thesedays, I started to use firefox from chrome.

Whenever I tried to access twitter, facebook, It display warnaning message with error message, sec_error_unknown_issuer. I think it is because of certificate of the sites, there wasn't exception button to add the site to use with warning message.

It is very wierd that these popular websites are blocked. I would like you to inform the solution, or I have to go back to the chrome instead of firefox.

the message I got .(in korea) 본 연결은 신뢰할 수 없음 Firefox가 안전하게 twitter.com로 연결하려고 하지만 실제 보안이 이루어지는지 확인할 수 없습니다. 일반적으로 안전한 연결을 할 때 웹 사이트는 신뢰된 인증 정보를 제공하여야 하지만 현재 사이트는 이러한 확인 정보를 제대로 보내주지 않고 있습니다.

고려할 사항 만일 지금까지 문제 없이 현재 사이트에 계속 접속했다면 이 오류는 누군가가 웹 사이트를 공격했을 수 있으므로 가급적 계속 접속하지 않기를 권장합니다. 이 사이트는 엄격한 보안 전송 HTTP(HSTS)로 Firefox가 안전하게 연결하도록 지정했습니다. 이에 따라 이 인증에 예외를 추가할 수 없습니다.

In English Translation(with google translate) This connection can not be trusted Firefox is trying to connect securely to twitter.com, but can not determine whether the actual security are made. In general, a web site must provide a trusted authentication information when a secure connection but this site can send these without properly identifying information.

consideration So far, ten thousand days without problems, this error is if you continue to have access to the current site can attack anyone have a website, we recommend that you do not stay connected as much as possible. This site has specified that Firefox is securely connected to the stringent security transfer HTTP (HSTS). As a result, you can not add an exception to this certification.


Many Thank!

There is security software like Avast and Kaspersky and BitDefender and ESET that intercept secure connections and send their own certificate.

If you can't inspect the certificate via "I Understand the Risks" then try this:

Open the "Add Security Exception" window by pasting this chrome URL in the Firefox location/address bar and check the certificate:

  • chrome://pippki/content/exceptionDialog.xul

In the location field of this window type or paste the URL of the website.

  • retrieve the certificate via the "Get certificate" button
  • click the "View..." button to inspect the certificate in the Certificate Viewer

You can inspect details like the issuer and the certificate chain in the Details tab of the Certificate Viewer. Check who is the issuer of the certificate. If necessary then you can attach a screenshot that shows the certificate viewer.
