Since upgrade to 41.0.1 for Mac OSX, I've been getting "untrusted connection" for many sites including Mozilla.

Recently upgraded to Firefox 41.0.1 for the Mac OSX (10.6.8) and I now get the "This Connection is Untrusted on many sites... including Mozilla, Facebook and many others. Have tried a Firefox "Refresh" and rebooted my system several times.

If you have Avast then try to disable HTTPS scanning in Avast Web Shield.

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.
