How can I inspect a https zert with firefox 151.0.1 (64-bit)

I'm used to check certs with right click on icon beside the address. Also for own servers in my local LAN I need this. I know there is Let's Encrypt. But sometimes it's more easy to just have a self signed cert and verify it myself. Also I want to see, who signed a cert from www.snakeoil.com/insert_your_credetials.

Please help.

Only connections that can be established will have the security details to show the cert info.

So for literally https://www.ssllabs.com/ssltest/analyze.html?d=www.snakeoil.com the TLS handshake is totally invalid and the cert can't even be checked for the chain etc.; you'd need to go more low–level to understand what this exact site is sending in response — a browser is unable to even parse that.
