With a valid certificate and no unencrypted elements, I am getting gray triangle on my site in Firefox. Why?

My site is getting a gray triangle icon despite the lack of any other elements that could be construed as unencrypted. While trouble shooting the issue, I created a page that contains only one line of text in a

tag and I am still getting the gray triangle. The certificate is valid and other browsers have no issue with the site. Certificate is SHA1, RSA 2048, and expires in August of 2015. According to research SHA1 should still be good until January of 2016. Is there something else that I am missing?

The URL for my test is here:

Firefox 36 will display a gray exclamation triangle if (1) there is mixed content in the page -- that's not new -- or (2) the server is configured to use RC4 as the encryption cipher and Firefox isn't able to negotiate a stronger cipher -- this is new in Firefox 36.

Unfortunately, Firefox doesn't have a direct error message on this; it just points to #1 and #2 above in general terms. If you open the page in Chrome and click the padlock in the address bar, you usually can find the RC4 issue buried in the Connection information. An example is attached for reference.

Oh, thanks for the URL. You also can view this report (link broken for posting):

In the Configuration section, there are two issues:

(1) TLS 1.0 is the highest protocol. This will cause the server to be inaccessible in Firefox 37.

(2) RC4 is the only cipher option. This is generating the warning in Firefox 36.
