torproject.org using insecure ciphers/protocols (SSLv3, 3DES and RC4)

I just tried to update Tor Browser in Whonix on Qubes OS and got this error: "curl_status_message: [35] - [SSL connect error. The SSL handshaking failed.]".

I looked at it a bit closer and it looks like https://www.torproject.org is currently using insecure ciphers.

Firefox Nightly tells me the cipher in use is:

TLS_RSA_WITH_3DES_EDE_CBC_SHA

And https://www.ssllabs.com/ssltest/analyze.html?d=www.torproject.org tells me:
