Cloudflare trying to use SSLv3?

when i connect with curl i get a sslv3 error in curl; when i connect with firefox i get SSL_ERROR_NO_CYPHER_OVERLAP which basically means “server didn’t offer any tls versions supported by firefox”; when i connect with Chrome i get

**** uses an unsupported protocol.


Unsupported protocol
The client and server don't support a common SSL protocol version or cipher suite.

which means basically the same thing; seems it’s using some version not supported by Chrome nor Firefox, and curl spout some sslv3 errors when trying to connect to it;
