Why cannot find out Tor Browser's SSL handshake at the default local Tor socks5 proxy port?

I get a message of Invalid filter: "tls.handshake" is neither a field nor a a protocol name.

Sounds like your Wireshark is pretty outdated.
Either way, try frame contains "torproject" or just tcp.port == 9150.
