I am trying to reach an internal company website (www.gqma.drw), with a certificate chain rooted in a company certificate authority. This works fine in Chrome, and worked in Firefox on my previous computer. But i recently got a new machine, and something somewhere is not quite right. I get an error message looking like this (between the ~~~s):

~~~ Someone could be trying to impersonate the site and you should not continue.

Web sites prove their identity via certificates. Firefox does not trust www.gqma.drw because its certificate issuer is unknown, the certificate is self-signed, or the server is not sending the correct intermediate certificates.

Error code: SEC_ERROR_UNKNOWN_ISSUER

View Certificate ~~~

If i click on the error code, i get these details:

~~~ https://www.gqma.drw/

Peer's Certificate issuer is not recognised.

If i click 'View Certificate', i get a chain of three certificates:

  1. Subject common name = *.gqma.drw, issuer common name = SSDNS CA, subject key ID = BE:EC:EA:22:CD:4E:D6:2A:07:4F:7A:85:FA:89:52:67:77:43:B1:E1
  2. Subject common name = SSDNS CA, issuer common name = ISS Root CA, subject key ID = 8C:60:FD:78:C7:B3:FD:59:0B:73:99:E5:36:48:3F:53:A7:41:82:65
  3. Subject common name = ISS Root CA, issuer common name = SS Root CA, subject key ID = 80:DD:C6:A2:AC:82:4F:FE:8A:19:2E:AA:EA:F8:BF:61:48:DC:31:73

If i go to Settings > Privacy & Security > View Certificates > Authorities, i can find both the SSDNS CA and ISS Root CA certificates. As far as i can tell, they are identical - i can open the certificate from 'View Certificate' and the corresponding one from the certificate manager and flip between tabs, and all the details are the same.

I am using Firefox 120.0, via a flatpak, on Ubuntu 22. I have given the flatpak access to /etc/ssl/certs, where my company's internal CA certificates are located.

To me, this seems like it should all work. The server has a certificate signed by an internal CA, which is signed by another internal CA, and both those internal CA certificates are in my certificate manager. So what is going wrong? Is there any way i can debug this?

From the developer:

> Is the root CA they've identified in the certificate manager is marked as being trusted for websites?

This is something that would be better served as a bugzilla bug.

Can you open a bug here:

And let me know the bug number? I'll get the devs involved.

Aha! The certificates were not trusted for websites, and after i marked them as such, everything works fine. Thanks!

I have opened a bug, because i think the error message here could be better: https://bugzilla.mozilla.org/show_bug.cgi?id=1867771
