Why is my self-signed certificate not recognized, even though it's in the Windows Certificate Store, and I've enabled security.enterprise_roots.enabled?

Hey all,

The certificate in question is one that's issued through TomCat, in accordance with [Confluence's instructions about how to issue a self-signed certificate](https://confluence.atlassian.com/doc/running-confluence-over-ssl-or-https-161203.html). I've also deviated from those instructions in order to add a Subject Alternative Name, so that Chrome doesn't complain.

As you may have guessed, this certificate is for a Confluence installation.

I've next used a Group Policy Object to deploy this certificate to every computer in our domain. Computers accessing the local Confluence website from Internet Explorer, Edge, and Chrome have no certificate errors. However, computers accessing this local Confluence website from Firefox (currently, version 57) give error: ``` https://[host.domain]:[port]/

Peer’s Certificate issuer is not recognized.

HTTP Strict Transport Security: false HTTP Public Key Pinning: false

Certificate chain: ```

I am aware of the [security.enterprise_roots.enabled](https://support.umbrella.com/hc/en-us/articles/115000669728-Configuring-Firefox-to-use-the-Windows-Certificate-Store) boolean flag, and have been able to enable it successfully. Specifically, there are some other internal websites that I didn't set up, but that we also distribute certificates for via Group Policy Objects. When this **security.enterprise_roots.enabled** is **true**, Firefox can visit those other internal websites without a certificate error, but when it is **false**, Firefox gives a certificate error when visiting them.

Was there a certificated in FF that you saved as well? Sometimes sites ask you to confirm and save their certificated to access the site as well. Was that missed?

Hey WestEnd, this Firefox hasn't saved any security exceptions.

That's by design, since I would prefer to handle certificates via Group Policy Objects, and the Microsoft Certificate Store.

To reiterate, Firefox does seem to be respecting the Microsoft Certificate Store when security.enterprise_roots.enabled is set to true, but not for this particular certificate issued through Tomcat.
