eBay Sponsored links. Shadow DOM #2297

JSCFORCE · 2022-09-27T21:32:43Z

Prerequisites

I verified that this is not a filter list issue. Report any issues with filter lists or broken website functionality in the uAssets issue tracker.
This is not a support issue or a question. For any support, questions or help, visit /r/uBlockOrigin.
I performed a cursory search of the issue tracker to avoid opening a duplicate issue.
The issue is not present after disabling uBO in the browser.
I checked the documentation to understand that the issue I am reporting is not normal behavior.

I tried to reproduce the issue when...

uBO is the only extension.
uBO uses default lists and settings.
using a new, unmodified browser profile.

Description

eBay uses the shadow DOM to mark certain listings as SPONSORED.

we can't remove them since we can't target the shadow DOM.

Since sites don't get much bigger than this is is time to add support for a :shadow-root(...) operator?

A specific URL where the issue occurs.

https://www.ebay.com/sch/i.html?_from=R40&_nkw=houses&_sacat=0

Steps to Reproduce

Any attempt to target or distinguish the sponsored listings from the normal ones fail.

Expected behavior

Normally removing an ad would be a snap but not when the CSS is hidden from us.

Actual behavior

Can't remove the sponsored ads with uBlock origin in its current form.

uBO version

1.44.4

Browser name and version

Vivaldi 5.4.2753.51

Operating System and version

Windows 10.0.19044.2006

The text was updated successfully, but these errors were encountered:

gwarser · 2022-09-28T05:27:59Z

Can you capture DOM tree with this shadow element? I don't see them in Firefox and Chrome. Only "Sponsored" text in every list entry, but hidden in non-sponsored offers.

mapx- · 2022-09-28T05:38:36Z

peace2000 · 2022-09-28T07:08:22Z

Also another major service, Facebook has started to use shadow dom: #2280

Text "Sponsoroitu" means "Sponsored" in English. Filters can't identify sponsored posts anymore on Facebook.

krystian3w · 2022-10-03T13:27:28Z

Also I don't found active shadow dom at eBay.

Strange is that page fastly dorpped use span:first-line - maybe script often change method to show text "sponsored".

eBay is definitely still using shadow DOM.

krystian3w · 2022-10-03T18:04:04Z

≈30 day ago used :first-line but AdGuard and uBo still don't added this to stable and IMO ABP don't added filter to anti-cv project to these fastly rewrite page.

When they detect adding it in the "beta" they can become a page similar to "soft98.ir".

ethan-xd · 2022-10-09T04:55:12Z

I have a filter that blocks Facebook ads, however the attributes are removed by Facebook. Yet another example as to why we need a straight up :remove() filter. Facebook can't fuck with what's not there anymore.

:remove() is already supported.

krystian3w · 2022-10-09T11:10:41Z

https://github.com/gorhill/uBlock/releases/tag/1.26.0

Add procedural cosmetic operators remove() and upward()

or this no works on shadow DOM?

Or we misunderstood "straight up" as "no implemented at all".

?? What??? I looked over for documentation and couldn't find it, I could only find issues saying that it wouldn't be added. Oh well. lol

ethan-xd · 2022-10-13T04:59:30Z

I don't get how I couldn't find this, I looked for like half an hour. Okay, thank you everyone for letting me know.

gwarser · 2022-10-22T10:15:38Z

For me, this span:

<span aria-hidden="true"><wbr>Sponsored</span>

when width is set by var(...) to ~58px (as reported by getComputedStyle, it's 98% in the variable), then "Sponsored" is hidden, but when is set to ~59px, it's shown.

No shadows in Chrome or Firefox.

krystian3w · 2022-10-22T13:53:53Z

But :matches-css(display: inline) e.g. with has-text works?

JSCFORCE · 2022-10-23T01:51:18Z

This works on Chrome and Firefox:

www.ebay.com##.clearfix.s-item__wrapper span[aria-hidden="true"]:matches-css(height: 20px):upward(.clearfix.s-item__wrapper):remove()

The following filter is a little better, removes some whitespace your filter leaves behind.

www.ebay.com##.clearfix.s-item__wrapper span[aria-hidden="true"]:matches-css(height: 20px):upward(li.s-item):remove()

but still we need a shadow root operator as soon as possible since this filter is very fragile.

I hope gorhill can get to this as soon as he has a free moment.

JSCFORCE · 2022-10-29T02:57:26Z

The above filter is no longer valid.

JSCFORCE · 2022-11-02T03:23:22Z

Any update?

krystian3w · 2022-11-02T11:24:59Z

This is maximum of move: -7556482px?

gwarser · 2022-11-02T11:28:59Z

Ah, no, just random, you can try simply hiding or removing - this part was left from my other attempts.

fyrefyre · 2022-11-02T19:51:41Z

!#if env_firefox
www.ebay.com##li.s-item span[aria-hidden="true"]:matches-css(width: /58\.|62px/):upward(li.s-item):style(position:absolute!important;left:-7556482px!important;)
!#endif
!#if env_chromium
www.ebay.com##li.s-item span[aria-hidden="true"]:matches-css(width: /59\./):upward(li.s-item):style(position:absolute!important;left:-7556482px!important;)
!#endif

?

Chrome, it's a bit hit or miss. Occasionally it removes just Sponsored. Other times it doesn't remove any. And then other times, it removes everything like:

JSCFORCE · 2022-11-03T03:50:42Z

Yeah that new filter break this page with chrome.
https://www.ebay.com/sch/i.html?_from=R40&_nkw=knives

Works or breaks it randomly.,..

None of these are good enough, we just don't have the proper tool to address this issue.

krystian3w · 2022-11-03T13:24:00Z

Maybe filter works good with GNU/Linux fonts.

gwarser · 2022-11-03T16:44:44Z

You can try setting font-face and fixed size for this element. Even reset some values by https://developer.mozilla.org/en-US/docs/Web/CSS/unset#see_also

Maybe filter works good with GNU/Linux fonts.

Does not work on second page of the results :)

krystian3w · 2022-11-03T18:09:40Z

Modern browsers added https://developer.mozilla.org/en-US/docs/Web/CSS/revert when unset does not exist

JSCFORCE · 2022-12-05T19:32:01Z

Does anyone have any update on this issue? I am absolutely sick of seeing ads on ebay. We need a proper and permanent solution to this!!!

JSCFORCE · 2022-12-06T03:45:23Z

I will gladly pay you 100 dollars right now for a proper solution. Just say the word.

@JSCFORCE try these

Ebay employees are likely watching this thread though

Clearly I am not doing this for money, so I suggest you fork and contract another developer.

JSCFORCE · 2022-12-06T15:31:39Z

@gorhill

I was trying to have a conversation. I am desperate and was simply responding to your original comment in the only way I know how. i.e. literally.

krystian3w · 2022-12-06T19:12:34Z

Github no support direct reply to specific comment in issue - discussion does because is similar to reddit.

But notification on reddit works better than gerneric in any Github discussion.

Shadow root/dom won't escape us anyway as msn already applies it to every embedded object on the homepage #2215 #2252 #2346.

It is enough that the advertising code escapes the possibility of aost.

www.ebay.com##.clearfix.s-item__wrapper span[aria-hidden="true"]:matches-css(height: 20px):upward(li.s-item):remove()

:remove() doesn't work on elements inside shadowRoot.

:remove() doesn't work on elements inside shadowRoot.

Still no shadows on my side.

Add a scriptlet to inject stylesheet into shadow DOM

But specific filters work in uBO. ?

uBlock-user · 2023-01-19T15:02:44Z

Still no shadows on my side.

I was speaking about my experience with shadowRoot, not specific to ebay here.

krystian3w · 2023-01-19T17:12:48Z

I can hide borders on MSN.com with generic filter on opened shadow DOM/root:

##msft-article-card[class=""]

So scriptlet unlock use long CSS path or for only closed shadow DOM/root?

pavelmalik · 2023-01-20T12:25:29Z

Any update on this? I've been using Stylus with approach , but obviously removing the nodes from the tree would be preferable

abp-filters/abp-filters-anti-cv#946 (comment)

gwarser · 2023-01-20T13:32:35Z

@pavelmalik

ebay.com##.s-item__detail--primary:last-child *:style(font-weight: 900 !important;color: red !important;font-size: 220px;line-height: 1.15;)
ebay.com##.s-item__detail--primary:last-child > * > *:style(bottom: 1em !important;left: 0px !important;)
ebay.com##.s-item__detail--primary:last-child > * > * > * > *::before:style(content: "████";)

Does not work.

krystian3w · 2023-01-20T13:44:13Z

Works under body: https://user-images.githubusercontent.com/35370833/213710303-98c84f4f-13be-407f-be52-a4e289583bb7.png

Maybe glitch in tabs.insertCSS() (scripting.insertCSS()).

pavelmalik · 2023-01-20T13:50:34Z

The actual one I'm using

@-moz-document url-prefix("https://www.ebay.com/") {
 .s-item__detail--primary:last-child * {

        font-weight: 900 !important;

        color: #fff0 !important;

        font-size: 220px;

        line-height: 1.1;

    }

    .s-item__detail--primary:last-child > * > * {

        bottom: 1em !important;

        left: 0px !important;

    }.s-item__detail--primary:last-child > * > * > * > *:before {

        content: "█████";

    }
}

gwarser · 2023-01-20T16:12:01Z

Works under body

And other entries down below? The whole page is marked red for me.

The actual one I'm using

This one looks OK

ebay.com##.s-item__detail--primary:last-child *:style(font-weight: 900 !important;color: #fff0 !important;font-size: 220px;line-height: 1.1;)
ebay.com##.s-item__detail--primary:last-child > * > *:style(bottom: 1em !important;left: 0px !important;)
ebay.com##.s-item__detail--primary:last-child > * > * > * > *::before:style(content: "█████";)

liamengland1 · 2023-01-20T17:48:51Z

this filter also works :P

ebay.com##li.s-item:has(.s-item__detail:nth-last-of-type(1):has(>span>span>span[aria-hidden="true"]:matches-css(width:/5[89]\.[0-9]+/):matches-css(border-right-width:/0\./):not(:matches-css(width:/5[0-7]\.[0-9]+/):matches-css(border-right-width:/1\./)):has(wbr+span))):not(:has(symbol)):remove()

That filter does not work for me.

liamengland1 · 2023-01-21T04:36:13Z

That filter does not work for me.

Sorry that it didn't work for you, it worked for me as you can see in this video. It's possible (likely?) that eBay slightly varies the DOM and CSS values so that this filter is not consistently effective.

krystian3w · 2023-01-21T09:28:51Z

But we use 1 line = 1 product.

stephenhawk8054 · 2023-02-10T04:59:45Z

I see that in the href of sponsored product, the length of the end characters after %3A are shorter than normal products.

Can anyone test

www.ebay.com##li.s-item a.s-item__link[href]:matches-attr(href="/%3A\w{12}(&.+)?$/"):upward(li.s-item)

?

If {12} doesn't work, try {11,13}

Appears to be working.

doesn't work here:

sigh, what a mess.

doesn't work here: https://www.ebay.com/sch/i.html?_from=R40&_nkw=ti-85&_sacat=0&rt=nc&LH_ItemCondition=3

sigh, what a mess.

It's because of the &LH_ItemCondition=3 at the end.

Test

www.ebay.com##li.s-item a.s-item__link[href]:matches-attr(href="/%3A\w{12}(&.+)?$/"):upward(li.s-item)

This takes care most of the sponsored products except few products at the top in some searches for me.

@gwarser idea works for me too

www.ebay.com##li.s-item .s-item__detail--primary span[role="text"] > span:matches-css(width: /59\.[5-9]/):upward(li.s-item):remove()

But at this point, it just depends on each person's DOM.

Can this help?

rileyvel · 2023-11-03T14:33:51Z

None of the above still works after eBay's updates. However, window.find can be used to infiltrate closed shadow DOMs - see https://book.hacktricks.xyz/pentesting-web/xss-cross-site-scripting/shadow-dom

I created a proof-of-concept that can be used as a userscript to remove eBay sponsored search results: https://gist.github.com/rileyvel/7162ed1049420e68c0913e52d220366b
Works on Chromium and Firefox, but not Safari.

Maybe ublock origin can use this to enforce :has-text filters globally?
Otherwise, filter lists can be asked to provide selectors of elements expected to host closed shadow roots (in eBay's case, span.s-item__sep > div). chrome.dom.openOrClosedShadowRoot can then be used to create "portals" between the light DOM and shadow DOM, and cosmetic filters can pass right through.

JSCFORCE · 2023-11-03T16:25:43Z

Amazing! Thank you for your detective work and making the script. I can confirm it does indeed work.

I would like to subscribe to your newsletter sir!

gorhill · 2024-04-15T13:17:21Z

Please evaluate whether issue can be closed with gorhill/uBlock@52b46eb.

krystian3w · 2024-04-21T17:55:16Z

They can do the creating shadow DOM-s/roots (as childs) in a loop to avoid single exposure.
