Add AdGuard's noopvmap-1.0 equivalent as a redirect resource

[Yuki2718]

Prerequisites

• I verified that this is not a filter issue
  • Filter issues MUST be reported at filter issue tracker
• This is not a support issue or a question
  • Support issues and questions are handled at /r/uBlockOrigin
• I performed a cursory search of the issue tracker to avoid opening a duplicate issue
  • Your issue may already be reported.
• I tried to reproduce the issue when...
  • uBlock Origin is the only extension
  • uBlock Origin with default lists/settings
  • using a new, unmodified browser profile
• I am running the latest version of uBlock Origin
• I checked the documentation to understand that the issue I report is not a normal behavior

Description

AdGuard Japanese addressed AdguardTeam/AdguardFilters#70829 by redirecting XHR to noopvmap-1.0, which indeed works. uBO doesn't have a counterpart so only way to fix this is allowing the request - redirecting to other resources such as noop.txt doesn't work. To be fair, allowing the request doesn't bring actual ads and uBO version of AG Japanese doesn't include the redirect filter so it's not a serious problem but a suggestion.

A specific URL where the issue occurs

https://tver.jp/corner/f0064327 (geo-locked)

Steps to Reproduce

1. Visit the site using Japanese VPN with uBO and AdGuard (Chromium extension) each.
2. If you get a modal, close by clicking upper-right X button (or "あとで" on bottom).
3. Play the video and see AG solution works on AG. No breakage on uBO too as both uBlock Unbreak and AGJPN has whitelist, but if you badfiltered them the player doesn't work. Redirecting to other resources doesn't work either.

Expected behavior:

AG Japanese' redirect works on uBO too.

Actual behavior:

Doesn't work.

Your environment

• uBlock Origin version: 1.32.0
• Browser Name and version: Firefox 84.0.1/Brave 1.18.75
• Operating System and version: Windows 10

Note

I'll remove the whitelist from Unbreak. If this suggestion is accepted and the resource is added, I can make PR on AG for them to include uBO for the target of the redirect filter.

Basically:

<vmap:VMAP xmlns:vmap="http://www.iab.net/videosuite/vmap" version="1.0"></vmap:VMAP>

Of note, AG Base has 2 filters redirecting to this. They excludes uBO.

!+ NOT_PLATFORM(ext_ff, ext_ublock)
||v.fwmrm.net/ad/g/1?resp=$xmlhttprequest,redirect=noopvmap-1.0,domain=viafree.dk,important
!+ NOT_PLATFORM(ext_ublock)
||api.jtbc.joins.com/ad/vmap/*$xmlhttprequest,redirect=noopvmap-1.0,domain=tv.jtbc.joins.com,important

They also have noopvast, what does that help fix ?

[gorhill]

I could not test that it works, feedback about this is welcome.

[Yuki2718]

Shortly tested on Firefox, the player doesn't work but AG also excludes Firefox:

!+ PLATFORM(windows, mac, android, ext_chromium)
||pubads.g.doubleclick.net/gampad/ads?*&output=xml_vmap$xmlhttprequest,redirect=noopvmap-1.0,domain=tver.jp

Screenshot

I'll test on Chromium tomorrow.

Working fine on Chrome:

So there must be reason that AG guys excluded Firefox. Maybe we can add Firefox-specific whitelist in Unbreak, but then the benefit of this resource will be halved - only for Chromium.

[uBlock-user]

on viafree.dk CORS is preventing data: resources from getting loaded on Firefox.

On https://funny-ai.com/46133611 after you uploaded a face photo and then clicked "ランキングを見る" button, I confirmed ||serving.stat-rock.com/v1/placements/$xmlhttprequest,domain=funny-ai.com,redirect=noopvast-3.0 can be used instead of an exception and media redirect I added in AdguardTeam/AdguardFilters@04aca97 to see rankings. noopvast works but shows error so I didn't added the rule even for AG just in case, but this can be used as a real case to test.
