We use Chrome and IE, Edge and have no issues with the SSL certificate and it shows green and valid. When we use the Firefox browser it thinks the certificate is invalid when it is not.

This is a site on our LAN at our corporation and we use a PKI Certificate environment on our network that has all the root and intermediate certificates added to the appropriate stores on the PC's and Laptop's.

Chosen solution

You have to configure Firefox to see the Windows certificate store. Unfortunately, this isn't enabled by default.

Try the following:

  1. Type about:config in the Firefox address bar
  2. Bypass the warning
  3. Change the security.enterprise_roots.enabled value to true
  4. Restart Firefox

Hopefully this fixes the issue.

If you are deploying this on a network with multiple computers, once you have verified that the steps work, you may want to explore using an AutoConfig file to make the required changes to all systems on your network.

Firefox can’t find the server at cpmas-uccxdc01.cintas.com.

Please explain the problem in detail. What happens? What is the exact error messages?

Note: Windows users should download the ActiveX for Internet Explorer. and the plugin for Plugin-based browsers (like Firefox).

Note: Windows 8 and Windows 10 have built-in flash players and Adobe will cause a conflict. Install the plugin only. Not the ActiveX.

This website is likely not accessible: This is a site on our LAN at our corporation.

Does Firefox provide any detail about the error (if necessary then click Advanced)?

it is a local Cisco Finesse agent application on our lan. You cannot get to it externally just Internally. the local certificate works in IE, Edge and Chrome but we get an invalid certificate when using Firefox even though it is not an invalid certificate.

I have uploaded pics showing valid from chrome but invalid from Firefox.

The two screenshots you provided do not show an error message. Where do you see this error message? Is there a problem with the certificate chain or doesn't Firefox has the root certificate?

You can try to set this pref to true on the about:config page in case other software adds its root certificate to the Windows certificate store.

  • security.enterprise_roots.enabled = true

You can open the about:config page via the location/address bar. You can accept the warning and click "I accept the risk!" to continue.
