Likely to me it's your ISP and they're DNS provider doesn't hold that site's data in it's current holdings so it has to find and download that website before sending you there. With so many millions of sites out there now it's likely the storage the dns provider uses is at capacity and if the site isn't a top site for visitors as in 10k hits a day plus for the dns servers then they wait for a request for those sites before getting updated data. If enough people go to the site regularly then the dns providers system will add the site to the list when it's higher up in popularity like number 5000 on Alexa for popularity would make it more likely to be accessed immediately.
Another message that I've gotten lately is the danger no certificate for this website which is actually the site likely being to broke to pay for certification from CA or where ever they get it. I always just bypass the stupid stop the browser does since it's just not registered and not some danger just haven't paid the tech lords dues this period so it's good with me.
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.
