1427324 - Firefox slow in rendering local (dev) site

Status: RESOLVED WORKSFORME

(Core :: Networking: DNS, defect)

Description

[Albert Scheiner [:alberts]]

My main dev browser is FF Nightly (59). When I started up Safari and Chrome to test something on the site I am working on atm, I realised how much slower Firefox is in loading from my local than the other browsers.

I checked the network panel and found this 
DNS resolution: → 5002 ms

In Safari and Chrome these are instantaneous, therefore the page loads super quick.

What might be the cause for this?

My local domain is https://website.local set in the hosts file on my mac (OS 10.12)

Hi Albert,

It seems that you can reproduce this easily. Could you try to capture the HTTP log according to [1]?
Thanks.

Hey Kershaw,

I actually wasn't able to replicate these long delays today. Nevertheless I created a new, clean profile and logged a requests for my local domain "website.local" (while having devtools open and cache switched off via network panel). I'll attach it in a sec. Feel free to close the bug if there is nothing out of the ordinary - I will keep an eye out. If it comes up again I'll try to log directly and might reopen this task.

Thanks
