I see a mention of this message that could be a possible cause:

  • Server negotiated HTTP/2 with blacklisted suite

It works for me in Firefox 45 if I disable HTTP2 by setting this pref to false on the about:config page, otherwise the page stays blank.

  • network.http.spdy.enabled.http2 = false

You can use the button on the "Help -> Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page.
