I'm getting the same error from Firefox, no cipher suite overlap. But I can see in Wireshark FF's ClientHello, and some of the cipher suites in that ClientHello seem to appear in the output that nmap says is the server's available cipher suites. So, I am perplexed. (And I'm on Arch; my FF can't be too far behind.)
