My website works fine on Chrome, but on Firefox there's a `SEC_ERROR_UNKNOWN_ISSUER` error with my SSL certificate.

My website is https://miroware.io/. In Chrome, it loads fine, and the SSL certificate works perfectly. In Firefox, there's an error. The section at https://support.mozilla.org/en-US/kb/troubleshoot-SEC_ERROR_UNKNOWN_ISSUER#w_missing-intermediate-certificate explains what the error is, but not how to fix it. Can I fix it? If so, how?

Oh! Never mind. I fixed it by applying a CA value in my Node server, setting it to my `chain.pem` file.

There is security software like Avast, Kaspersky, BitDefender and ESET that intercept secure connections and send their own certificate.

I don't use any of this software and have already solved the issue myself. See above.

That was very good work. Well done.
