Are you still experiencing this? I am unable to replicate on the Firefox Developer Edition. Perhaps that has something about to be released in the regular channel?

Yes, still experiencing it on FF 35.0.1. It does an infinite loading while connecting to .
To be more clear, in about:config the values "network.http.sendSecureXSiteReferrer" and "network.http.sendRefererHeader" are set to default values.
