User Agent: Mozilla/5.0 (Windows NT 6.1; rv:41.0) Gecko/20100101 Firefox/41.0
Build ID: 20151014143721

Steps to reproduce:

Visit https://wikidevi.com/wiki/Main_Page
Then open the Certificate Viewer dialog.


Actual results:

The page shown correctly but the Certificate Viewer shows "Could not verify this certificate because the issuer is unknown." and only the server certificate shows in the Certificate Hierarchy.

I use "openssl s_client -showcerts -connect wikidevi.com:https" to dump the certificates and it lists 1 server certificate and 3 intermediate CA certificates. I also go to the https://www.sslshopper.com/ to check the site, it found the same result as openssl. I also learned that the final root CA certificate is "AddTrust External CA Root" is the built-in certificate in firefox. Below is the dump of the openssl command:

CONNECTED(00000003)
depth=4 C = SE, O = AddTrust AB, OU = AddTrust External TTP Network, CN = AddTrust External CA Root
verify return:1
depth=3 C = US, ST = UT, L = Salt Lake City, O = The USERTRUST Network, OU = http://www.usertrust.com, CN = UTN - DATACorp SGC

Expected results:

The Certificate Viewer should not show "Could not verify this certificate because the issuer is unknown." and the Certificate Hierarchy should list complete certificate chain.

What happens if you visit the site with a new profile?
Flags: needinfo?(super.dukefb1)
I found the problem may relate to the Private Mode. Below is my trials
1. Same profile with Private Mode, the problem occured.
2. Same profile with normal mode, no problem (*)
3. New profile with Private Mode, the problem occured.
4. New profile with normal mode, no problem (*)

(*) But firefox displays only 3 certificates in the Certificate Hierarchy:
COMODO Certificate Authority (Certificate Fields displays Builtin Object Token:COMODO Certi...)
  EssentialSSL CA (Certificate Fields no refresh the content)
    wikidevi.com (Certificate Fields displays wikidevi.com)

So, maybe there are another 2 problems
i. Firefox should completely display 5 certificates in the Certificate Hierarchy.
ii. Firefox should display the details for EssentialSSL CA in the Certificate Fields.
Flags: needinfo?(super.dukefb1)
I have additional information and correct one point of previous post.

Once I visited the site in normal mode, the Software Security Devices "EssentialSSL CA" and "DigiCert SHA2 Extended Validation Server CA" will be installed in the Authorities of the Certificate Manager. And then when I use Privete Mode to visit the site, it will be normal.

In the previous post, in the normal mode, it's no problem in the EssentialSSL CA's Certificate Fields. But the problem is that after I removed the "EssentialSSL CA" and "DigiCert SHA2 Extended Validation Server CA" from the Certificate Manager, close firefox, run firefox in Private Mode then visit the site. At this time, firefox seems normal, but when I check the "EssentialSSL CA" it has no refresh the Certificate Fields. The even interesting thing is that couple minutes later (I visited other sites in new tabs) the site (wikidevi.com) fall back to "Could not verify this certificate because the issuer is unknown." and the Certificate Hierarchy shows only wikidevi.com.
Thanks for looking into that. I can now reproduce the problem. I'll investigate further when I have time (and others can feel free to look into this as well - see comment 2 for STR).

Whiteboard: [psm-backlog]
Probably related to this bug:
Visiting some websites (e.g. https://kis.hosteurope.de/), firefox
sometimes shows a green padlock (without owner information) next to the URL.
In spite of the green padlock, the certificate viewer reports "Could not
verify this certificate because the issuer is unknown."

The same problem shows with the certificate hierachy as mentioned by the OP.

Reloading the website only sometimes reproduces this behaviour, while in 
other (apparently random) cases the green padlock plus owner information is displayed (as 
expected) and the certificate viewer does *not* show any errors/problems.

The certificate provided by the website is always the same, independently of
which case occurs.  I could live with false negatives in the certificate verification
process, but false positives (= green padlock with untrusted cert) is pretty dangerous!?

Firefox: 45.3.0esr-1~deb7u1, Debian wheezy, amd64

Previously posted: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=835476
(including screenshots), but without any replies.
Well, wikidevi.com uses Let's Encrypt now, and I can't reproduce the issue, so I'll close this as wfm for now.
