The certificate on my d-link smartswitch expired and i can no longer access the switch. There doesn't seem to be any way to add an exception or bypass this on firefox 44.

Hello try to toggle to true the next preference (in about:config) and see if that allows to add an exception (it is for bad certificates not for expired)

  • browser.xul.error_pages.expert_bad_cert

Can you inspect the certificate via the chrome URI?

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 with the https:// protocol prefix (https://xxx.xxx).

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

I cannot fetch the certificate in firefox 44 at all, it says no "information available" and "could not retrieve identification status".

In Ie11 or Edge it works fine and i can add an exception. When i check the cert details in Ie11 i can see it's a V3, RSA-1024/sha1 certificate that expired on january 8 2016.

It's like firefox 44 totally blocks sites with expired certs.
