Certificate Error only on Firefox only on one computer
Firefox is giving me an error on https://stemgateway.nasa.gov but the site is perfectly accessible using MS Edge and using Firefox on another computer. I uninstalled and reinstalled Firefox, changed the proxy settings to not use a proxy, tested a VPN, and changed DNS servers. Below is a picture of the error and of the certificate which seems to be present in Firefox already.

Yeah that's why I'm confused, I reinstalled Firefox multiple times as well as tried other derivatives such as Zen or PaleMoon. I also tried with/without a VPN and on different connections and browsers so I think I've isolated it pretty well to something with Firefox settings but I've turned on/off Proxy to no avail.
On the other hand, the STEM gateway site just opened without any other changes so I guess that's my issue solved? The only about:config value that's been modified was services.settings.security-state.intermediates.last_check in regards to security so maybe it didn't grab the store recently? I have no clue. Thanks for the help y'all.

Can you paste this certificate in text version - that option with PEM (chain)?

The site fails to serve the intermediate signing certificate. (Verified using https://www.ssllabs.com/ssltest/analyze.html?d=stemgateway.nasa.gov)
That used to cause a connection error in all installations of Firefox that hadn't previously cached the same certificate from visiting a site that served it properly. But starting in 2020, Firefox added a feature of preloading approved intermediate certificates. I don't know how to determine whether a specific certificate is in the file Firefox downloads, but I suspect this one is. The Mozilla blog post on intermediate certificate reloading (https://blog.mozilla.org/security/2020/11/13/preloading-intermediate-ca-certificates-into-firefox/) refers to the Common CA Database, and and "Sectigo RSA Domain Validation Secure Server CA" does appear in the (slow-loading) daily database report at
https://ccadb.my.salesforce-sites.com/mozilla/PublicAllIntermediateCerts
Intermediate cert preloading is enabled by the following preference in about:config (Configuration Editor for Firefox), which is set to true by default:
security.remote_settings.intermediates.enabled
Is yours disabled?
No I don't think so. Testing the same site on my Macbook results in a functional page even with that config setting disabled.

I don't think there is a way to make Firefox behave more strictly, so perhaps there is some other reason that Firefox isn't able to use (or isn't retrieving) the preloaded certificate.
