This does not help anything. I still cannot get in the desired web page still.

The Problem "Peer’s Certificate has been revoked"

The error message you are seeing in Firefox it means that the security certificate for the TÜV SÜD website has been officially cancelled (revoked) by the issuing authority (D-Trust). click Advance and > Error Code: SEC_ERROR_REVOKED_CERTIFICATE for details.

A certificate is usually revoked maybe from Security Breach or Replacement ot Administrative Error

Why does Chrome work while Firefox blocks it?

Firefox check's the status of a certificate in real-time. If the issuing authority says "this certificate is revoked," Firefox will block the connection immediately to protect you.

Chrome (and Edge) to save time and speed up browsing,doesn't always check the status of every single certificate in real-time. If that list hasn't been updated yet on your computer, Chrome will let you in, unaware that the certificate is actually invalid.

I suggest do not ignore the warning

There is nothing wrong with your computer or your Firefox settings. This is a server-side configuration error by TÜV SÜD.

I think their IT department (a large organization like TÜV SÜD) will fix it within a few hours by installing the correct, updated certificate.

This is a job portal where you upload sensitive personal data (CVs, address, phone number), I would advise to wait until the error disappears from Firefox. Using a browser that ignores a revoked certificate is technically a security risk.

Υou can contact the staff who posted the job advertisement for more information

Use it at your own risk
