probably a cache issue if it's a browser specific issue.
you can look at the fingerprint by clicking on the icon to the left of the URL address bar. Compare them between the two browsers to verify whether or not they are the same. If they are different, then it's a caching issue.
I just cleared my entire cache for pale moon and still invalid cert.
Check the fingerprint
The valid one I get starts
SHA-256 Fingerprint B2 F0 F0 0B 40 14 SHA-1 Fingerprint 2E C0 9F BF 04 A7
... how though? There is no cert from this browser. I've tried safemode and same issue so it's not an addon.
