The warning page options are: "Try again" and "Report this error". There is no "Advanced" button which would allow me to press "Add Exception..." and move to the "Add Security Exception" dialog. How do I deal with this roadblock? I would appreciate some suggestions. I use Windows 10 and Firefox 44. Tom at: tbenton1946@yahoo.com -- Thanks

Can you post a link to a publicly accessible page (i.e. no authentication or signing on required)?

Are there (i)frames used on the page if you check that via the right-click context menu?


If you can't inspect the certificate via Advanced (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 (https://xxx.xxx).

  • 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 please attach a screenshot that shows the Certificate Viewer.
