[Firefox] Yahoo Answers advertisments not blocking

[ghost]

All Yahoo advertisements on Yahoo Answers are loading with uBlock 0.8.6 installed using Firefox 35.

I tried to load Yahoo Answers in Google Chrome with uBlock and the advertisements are blocked sucessfully with the same filter lists enabled.

Examples of affected URLs are:
https://answers.yahoo.com/question/index?qid=20150130103427AAkfwzj
https://answers.yahoo.com/question/index?qid=20150130103543AAc6K87
https://answers.yahoo.com/question/index?qid=20150126110120AAPd5B4

Screenshot of advertisement:

The filters I have enabled in uBlock Firefox are:

Works fine here.

What are the two filters in your custom filters?

[ghost]

Ones for Tumblr:

||tumblr.com/video_file/*
||tumblr.com/*.gif

Edit: Tried deleting them, and refreshing page. The ads are still loading so I don't think it's those filters.

[gorhill]

Note that I don't see the other advertisements which one see if disabling uBlock. So it looks like a cosmetic filter issue.

Anything in your whitelist tab?

[ghost]

Just the defaults:

about-scheme
behind-the-scene
chrome-extension-scheme
chrome-scheme
data-scheme
file-scheme
opera-scheme

The request log shows a number of things being blocked so uBlock is doing some things.

Yes it looks like this ad requires a cosmetic filter. I would like to see the class/id/etc. If you use the element picker on it, I would like to see all the suggested cosmetic filters in the element picker dialog box. It could be a new layout not covered by the current EasyList.

For example I get:

###dmRosAdWrapper-MainNorth-iframe
###dmRosAdWrapper-MainNorth.mt8
###ad-case
###qa-case.qa-container
###yan-question
###ya-m
###ya-c.rapidnofollow
###ya-center-rail.y-col.y-col2-1
###ya-content-apps.ya-grid
###ya-main-content.y-col2
###ya-body-container.ya-grid
###ya

Here's what I get:

    Net filters
        about:blank
    Cosmetic filters Click, Ctrl-click
        ###dmRosAdWrapper-MainNorth-iframe
        ###dmRosAdWrapper-MainNorth
        ###yui_3_17_2_3_1423095504008_1933.Mstart-75.Mr-14
        ###ya-qpage-textads.Bgc-w.Pt-7.Mb-neg-10.Bdstart-1g.Bdend-1g
        ###ya-center-rail.Col2.Pos-a.Bxz-bb.Start-0
        ##.Answers
        ###MasterWrap

Strange. I can't find any of your selectors in EasyList. The ad on my side located at the same position is filtered out through EasyList's #ad-case. It's as if you stumbled onto a new Yahoo ad which is not covered by EasyList.

[gorhill]

How old is your EasyList? If you click on it in the 3rd-party filter lists, it will open whatever is being used.

[ghost]

EasyList is "Last modified: 05 Feb 2015 00:10 UTC"

[gorhill]

Maybe another extension is modifying the page? I really don't know what to say, as said, none of the selectors in there is a match in EasyList. You could report to EasyList maintainers but it might be kind of awkward for them to see uBlock was used. But the CSS selectors are really what matters, and they are no hit.

I uploaded the HTML Yahoo is using at https://gist.github.com/metaphoricgirrafe/ef9bb7e48a7801acb107

They are serving totally different HTML for Firefox and Chrome, perhaps this is the issue?

[gorhill]

What I reported above was with Firefox.

[gorhill]

Me:

<div id="ad-case">
<style> #dmRosAdWrapper-MainNorth iframe{width:100%}</style>
<div id="dmRosAdWrapper-MainNorth" class="mt8">

You:

<div id="yui_3_17_2_3_1423096017604_1911" class="Mstart-75  Mr-14">
<style>#dmRosAdWrapper-MainNorth iframe {width: 100%}</style>
<div id="dmRosAdWrapper-MainNorth">

The cosmetic filter in action here on my side is #ad-case (a generic one).

I just restarted Firefox and loaded up YA again and the ads are gone. I inspected the HTML and it is now the same as yours.

I had the same problem with ads showing up on Yahoo Answers yesterday, so it looks like they must of being giving me a new layout and reverted me back to the normal one.

[ghost]

Scratch that. I'm getting served advertisements again in Firefox.

The HTML is now slightly different:

<div id="ya-qpage-textads" class="Bgc-w Pt-7 Mb-neg-10 Bdstart-1g Bdend-1g">
    <div id="yui_3_17_2_3_1423105641477_1929" class="Mstart-75  Mr-14">
        <style> #dmRosAdWrapper-MainNorth iframe {
            width: 100%
        }</style>
        <div id="dmRosAdWrapper-MainNorth">
            <noscript>
                <iframe id="dmRosAd-1-north" width="560" height="315" frameborder="0"
                        marginheight="0" marginwidth="0" scrolling="no"
                        src="http://dmros.ysm.yahoo.com/ros/?c=580c58ad&w=678&h=315&ty=noscript&tt=$title&r=$keywords">
                </iframe>
            </noscript>
        <iframe scrolling="no" marginheight="0" marginwidth="0" src="about:blank" id="dmRosAdWrapper-MainNorth-iframe" frameborder="0" height="225" width="560"></iframe></div>
    </div>
</div>

Seems like I will have to apply a filter to #ya-qpage-textads

Thank you for also taking a look into this issue.

Edit: Blocking everything from the YA domain also disables these new ad displays
||answers.yahoo.com

[gorhill]

I suppose if #ya-qpage-textads is reported to EasyList, this would also benefit other users.

[ghost]

Alright, I've reported #ya-qpage-textads to EasyList

Note: Using #ya-qpage-textads as a rule leaves a flash of unstyled content but using ||answers.yahoo.com blocks it without the quick flash of ads during the load.

@metaphoricgirrafe - Looks like after a month, EasyList doesn't have your fix.
Can you please post it here, so I can manually add it to my blocker?

[gorhill]

What's your version of EasyList? I see it in there:

answers.yahoo.com###ya-qpage-textads 

"Last modified: 04 Mar 2015 12:10 UTC".

I checked, and it is also in the version of EasyList shipped with uBlock.

Edit: see https://hg.adblockplus.org/easylist/rev/16a4e027d6d1

[litehacker]

I see yahoo updated their ad. It's now id="ya-q-8657-textads"
I presume this number can vary.
