A browser has a set of CA certificates that it trusts. I don't know if and how it checks that set when it starts (certainly not before starting). Don't forget, there are many browsers, which may do things in different ways.

A web site's certificate is signed by a CA, and the CA's certificate is either self-signed or signed by another CA.

What you call "intermediate certificate" is a CA certificate.
What you call "CA" is a root CA.
See, for example, https://knowledge.digicert.com/solution/SO16297.html.
