Firefox reported secure connection: High-grade Encryption (RC4, 128 bit keys).
Went back to Opera, disabled TLS v1 Security protocol (left v1.1 and v1.2), and now Opera reports secure connection: TLS v1.2 256 bit AES (1024 bit DHE_RSA/SHA-256)
That's strange, wonder if Cloudflare are actively disabling vulnerable protocols.
