How can I get the SEC_Unknown_Issuer error page to display Decoded Certificates, in Firefox 52.9 (ESR) ?
Due to some extenuating circumstances, I routinely run into the SEC_Unknown_Issuer error page for security certificates. Under Advanced the page displays the full Certificate hash, but it would be nice if actual certificate details were displayed as well. Like the Certificates issuer.
As it stands now, I have to copy that hash value and then paste it into another website to decode the certificate, to see who the issuer was reported to be. https://www.sslshopper.com/certificate-decoder.html Why can't firefox do this for me?

I just discovered an add-on that may help me. https://addons.mozilla.org/en-US/firefox/addon/certificate-viewer-for-humans/?src=search
But why isn't this just baked in?
nevermind. the plugin doesn't work for me.
Good question. But support volunteers generally can't answer "why" questions. And why questions often are suggestions for feature changes in the guise of rhetorical questions. So with that in mind:
To submit feature suggestions, you could use one or more of the following (depending on whether you want a suggestion box or a discussion):
- Feedback: https://qsurvey.mozilla.com/s3/FirefoxInput/
- Reddit: https://www.reddit.com/r/firefox/
- Twitter: https://twitter.com/firefox
- Facebook: https://www.facebook.com/Firefox
You might also suggest it go into the developer tools panel. Their forum is over here:

Apparently the error page is privileged and extensions are not allowed to do anything in/to them. So it would need to be a change to Firefox.
