If it were the ISP and DNS then it wouldn't matter which browser you are using, all would be slow.
Unless Firefox uses another DNS server which, if i remember correctly, they do by default
This is true. That is why in firefox preferences I shut off all suggestions and Query OCSP responder servers to confirm the current validity of certificates is kept unchecked. Also I uncheck Block dangerous and deceptive content and then Mozilla is not holding my hand and approving my choices and https is on at all times.
