(Web Compatibility :: Site Reports, defect)

Description

[mytbk920423]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:57.0) Gecko/20100101 Firefox/57.0
Build ID: 20171114144214

Steps to reproduce:

Visit https://vimacs.taobao.com/ in Firefox 57.0, 58.0.b4 and 59.0a1.


Actual results:

The images don't show in the browser. The HTML code for the images are like this:

<dt class="photo">
                    <a href="//item.taobao.com/item.htm?id=551730324021" target="_blank">
                        <img data-ks-lazyload="//img.alicdn.com/bao/uploaded/i3/91590902/TB2.FfOXDAKh1JjSZFDXXbKlFXa_!!91590902.jpg_240x240.jpg" src="//assets.alicdn.com/s.gif" alt="...">
                    </a>
                </dt>


Expected results:

These images should show in the browser as in earlier versions of Firefox.

Those images are displayed as expected in Firefox nightly (59) on windows.
Are the images are still missing in the Firefox safemode ?

I would expect that an adblocker can cause this.

Not in nightly on Windows either. I did a fresh install and did a refresh after installing nightly and there's no addons.

It works on my system as you can see in my screenshot.
Does it work in older Firefox versions ?
Does it also work in a different browser on your system (to rule out filtering on the network layer) ?

I tried opening the same page in Firefox 57 and Epiphany, and Epiphany can display the images, but Firefox can't. Also, I tried Inspect Element and changed a "data-ks-lazyload" to "src" in the page, and the image shows again.

I also tried Firefox 54 in Linux Mint Live CD (linuxmint-18.2-cinnamon-64bit.iso), the images also cannot display in it.

Comment 7

[Matthias Versen [:Matti]]

I tried it on my Ubuntu 16.04LTS Box and also on my MAC mini with Firefox57 and the images are also loading as expected.

Did you try the safemode from comment#1 because that also disables video hardware acceleration and other things in firefox ?

Loading http://img.alicdn.com/bao/uploaded/i3/91590902/TB2.FfOXDAKh1JjSZFDXXbKlFXa_!!91590902.jpg_240x240.jpg works for you ?
Networking could be an issue with local Firewall/filtering on your side or because you get a different Server from the CDN but it can't be the reason if loading the direct URL works or if it works in another Browser.

I really don't know what to do next !

Comment 8

[mytbk920423]

This user script can solve the problem: https://greasyfork.org/zh-CN/scripts/35097-taobao-fix
I saw that the <img data-ks-lzayload=...> becomes <img src=...> after applying this script.

Also, when the problem happens, I can't find in Developer Tool that Firefox try to load the images.

Oh, I see your screenshot you're redirected to the *.world.taobao.com site, which is the same as the user script I mentioned above.

[Matthias Versen [:Matti]]

That I get redirected to a different site explains this :-(
There is no way for me to test this because I don't know how to avoid that redirect.

I've tried to reproduce the bug on all three firefox versions as you mentioned and here's my report.
I could not find 58.0.b4 so I've tested the website on 58.0.b3 and 58.0.b4.

OS: Ubuntu 17.10 64-bit

Case 1: 57.0
User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:57.0) Gecko/20100101 Firefox/57.0
Result: Bug cannot be reproduced and the images load as intended.

Case 2: 58.0.b3
User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:58.0) Gecko/20100101 Firefox/58.0
Result: Bug cannot be reproduce and the images load as intended.

Case 3: 58.0.b6
User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:58.0) Gecko/20100101 Firefox/58.0
Result: Bug cannot be reproduce and the images load as intended.

Case 4: 59.0.a1

From my testing I conclude that this bug cannot be reproduced on the Ubuntu 17.10 64-bit machine with above Firefox versions.

You are also redirected to the *.world.taobao.com site.
I think a Chinese IP is needed to reproduce this bug.

I opened a temporary socks5 proxy at tiny.cnjabber.net:1080, with which you'll not get redirected to the world site.
