ssl_error_no_cypher_overlap in Firefox developer edition, Warning Triangle in Firefox but working OK in Chrome

Firefox Jiné

When Browsing with Chrome to https://apollo.adc.uk.com the certificate shows fine and shows a SHA256 signed certificate.

In Firefox (36.0) it shows a grey warning triangle and the console shows "This site makes use of a SHA-1 Certificate; it's recommended you use certificates with signature algorithms that use hash functions stronger than SHA-1." and I cannot use firefox to show the certificate details.

In Firefox Developer Edition (38.0a2 (2015-03-01)) it shows an Error Page with Error code: ssl_error_no_cypher_overlap

We have been in contact with both our hosting company (who configure SSL termination on the LB) and the certificate issuers to ask for support but they report everything is OK as expected and they suspect a Firefox bug.

hi RichardCocks, this is no bug in the browser - your site only offers weak TLS_RSA_WITH_RC4_128_SHA encryption which should be considered broken. according to this recent proposal browsers have to stop supporting RC4: https://tools.ietf.org/html/rfc7465

starting with firefox 38, the browser will show the error message you've referenced on affected sites...
