Button to add exception not grayed out, but also not functional.
Upon my latest update to Firefox 56.0.2, I can not access the secure server where I keep my web site, receiving the "Your connection is not secure" error (the server owner prefers to keep it self-signed). In previous versions I've been able to add the exception, and the option is still there in this version; i.e., I see the "Confirm Security Exception" button and it's not grayed out. However, clicking on it has no effect, and I have no choice but to cancel. I can access the site using Chrome, but would rather not!

Try to rename the cert8.db file (cert8.db.old) and delete cert_override.txt in the Firefox profile folder to remove intermediate certificates and exceptions that Firefox has stored.
If that has helped to solve the problem then you can remove the renamed cert8.db.old file.
Firefox will store intermediate certificates that a server sends in the Certificate Manager for future use.
You can use the button on the "Help -> Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page.

I'm not sure why that is happening. What is the detailed error information in that panel where the button is?

Unfortunately, these replies didn't get past my spam filter, so I didn't see them until just now.
One interesting detail (that I didn't know at the time) was that my home computer (same OS, same version of Firefox), but I do not have this problem. Perhaps something specific to our University security set up, although I can still access the pages in question using Chrome at work.
Renaming and deleting the cert files as cor-el suggested did the trick. Thanks!
