1344086 - since i upgraded to firefox 51.0.1 the following web page is slow to load.

Status: RESOLVED INCOMPLETE

(Core :: Networking, defect, P3)

Description

[Jim]

User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:51.0) Gecko/20100101 Firefox/51.0
Build ID: 20170125094131

Steps to reproduce:

go to this web page
http://www.clickondetroit.com/weather/

 Firefox 51.0.1 64 bit will stop loading the page midway and hang while transferring data from the headers for about 3 to 5 mins
Happens on fresh startup or if you switch to another page and go back to this page


Actual results:

part of the page loads the satellite weather image takes forever to load. firefox seems to be waiting for headers to load and transfer data causing an unnecessary delay.You can watch the spinning wheel and see the transfers going nice and slowly as the page loads.


Expected results:

page used to ( In the previous version) and should load right away all headers should be grabbed at random and the slow ones bypassed so the page will load.

I can not reproduce this issue on the current release Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:52.0) Gecko/20100101 Firefox/52.0

Can you update your firefox and see if this issue is still happening?

Also can you go to about:support and past your graphics?

I upgraded to version 52 and the page won't load the graphics unless I minimize then maximize the browser. then it instantly loads. I have a JPG screenshot for you to see what I see. This is the graphic section.

In private browsing mode the page loads at full screen instantly.

[Kartikaya Gupta (email:[e-mail])]

This has nothing to do with WebRender. It sounds like a network issue, probably some slow tracking request that we skip in private browsing mode.

Comment 5

[Dragana Damjanovic [:dragana]]

I cannot reproduce it.

May I ask you to make a http log and upload file on send it to me per e-mail as you prefer:

Thank you!

I have tried to make a log but I can't seem to do it. I go to about:networking but the start logging is greyed out. I got this from the web console but I don't know if it will help. Is there another way to get you the information you need?

Jim, there is also another way - use environment variables:
https://developer.mozilla.org/en-US/docs/Mozilla/Debugging/HTTP_logging#Logging_HTTP_activity_using_environment_variables

Valentin, do you have any idea why [Start logging] would be greyed out?

That's because the env variables are also being used.
You can either use the environment variables for logging, or about:networking. Not both.

[Patrick McManus [:mcmanus]]

reporter please clear the env variables, restart and just use about:networking to get the log. thanks.
