Does the same happen here?


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

Open this chrome URI by pasting or typing this URI in the location/address bar to open the "Add Security Exception" window and check the certificate:

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

In the location field type/paste the URL of the website: https://accounts.firefox.com/

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

Check who is the issuer of the certificate. You can inspect more details like the certificate chain in Details tab of the Certificate Viewer.

Yes I have the same issue with https://accounts.firefox.com/signin even after adding and exception.

It shouldn't be necessary to add an exception.

Did you check the issuer and possibly other details to see what is wrong with the certificate?

Apparently Avast was stopping me from accessing the webpage. Thanks for the help!
