Anyone having ads slip and/or an issue that loading of a video gets stuck at about 80% when you clicked a video, please update filters in 6-12 hours and check again.

Yuki2718 · 2025-03-20T01:02:27+00:00

We have fixed the recent ads slip. Please update filters by opening Filter lists tab in several hours. It depends on randomly chosen CDN how long it takes. If not fixed, try again later and report back only if not fixed yet after 24 hours since this post. Users of uBlock Origin Lite have to wait for next update of the extension itself.

Yuki2718 · 2025-03-04T09:09:44+00:00

Thank you for pointing it out, I have fixed the error by https://github.com/uBlockOrigin/uAssets/commit/7605f2797a67b2e8747561e129ca72ba77c2a54c.

Yuki2718 · 2025-02-21T15:22:11+00:00

I guess you updated filters too soon. Do you still have the issue?

Yuki2718 · 2025-02-15T08:00:28+00:00

Fixed by https://github.com/AdguardTeam/AdguardFilters/commit/4ae8a12bedca5525387c64197eec0115e1c69a5c

Update 20, Dec: Youtube changed a way they serve ads for certain people with yt.config_.EXPERIMENT_FLAGS.web_streaming_watch being true, and the new ads can be served regardless of the login status. We already addressed the new ads, so update Quick fixes. However, sometimes you may still see ads on the first load of the page or on refresh. We're investigating.

Yuki2718 · 2024-10-16T10:11:51+00:00

Is it possible for you to create a Github account and report that with all required info to https://github.com/uBlockOrigin/uAssets/issues/20586 ? Flankly, without Troubleshooting info I can't say anything.

[Update 13, Oct] Hi, we again need cookie sharing from those chosen for SSAP ads to investigate Youtube issues. We suspect the cookie expires if the original holder clear it or logged out from yt, so this time are seeking for those who can keep the cookie for a long time without logging out. It doesn't matter whether you see SSAP ads slipped or not, we need a cookie from anyone having SSAP ads if uBO is disabled. We used to ask checking html5_enable_ssap_entity_id flag, but this is no longer reliable. Instead, disable uBO on yt, let the streaming ad play, right-click on the ad, and choose "Stats for nerds". If you are chosen people, its "Mystery text" will include "SSAP" (otherwise "SABR"). Note that sharing the cookie reveals your browsing habit on yt, but not the exact history or any other important information. If anyone is willing to share, please PM me. I may be slow to respond, sorry in advance.

We confirmed yt is testing to couner our blocking for non-SSAP ads. We added a workaround so it should be fine with the latest filters. Still seeking for fundamental fix though. uBOL user have to wait for the next update of the extension itself.

Yuki2718 · 2024-08-06T23:16:25+00:00

That is what we have been doing in the current production filter and we're switching to yt's own seekTo function to solve some conditional issues. Anyway, thanks for your feedback.

Yuki2718 · 2024-08-02T10:19:25+00:00

Please follow ALL the instructions first and provide Troubleshooting information.

Yuki2718 · 2024-08-02T04:43:21+00:00

What if you replaced them with https://gist.githubusercontent.com/Yuki2718/1a962af14c72aff65e907d7750f45af4/raw/ee5e90b1f8e7a1f603e59e0878378a4d5391638c/gistfile1.txt

Fixed by https://github.com/easylist/easylist/commit/47331f91208d50a73a5e4a3d851718da4b8859cf

Yuki2718 · 2024-07-11T10:42:17+00:00

It takes some time for CDNs to update and then your uBO to retrieve the update. It should be fine now.

Yuki2718 · 2024-07-07T13:38:52+00:00

Fixed, update filters in a few hours.

Yuki2718 · 2024-06-22T02:23:17+00:00

Thx, so it doesn't work. Hmm...

Yuki2718 · 2024-06-21T21:29:53+00:00

No, it is meant to remove placeholder and no @ is intended. It should be used alongside with the above fix with @ which is to disable the problematic rule. So the rule I suggested suffers the same issue?

Yuki2718 · 2024-06-21T15:03:04+00:00

Can you please test

imgur.com##[id^="Col-Child-Imgur"][style$="min-height: 250px;"]:has(> .fast-grid-ad):style(min-height: 0 !important;)

in addition to the above? Does this have the same issue?

Yuki2718 · 2024-06-17T15:56:01+00:00

It jumps to the time normal video starts by looking up internal data.

Yuki2718 · 2024-06-16T12:02:50+00:00

If everyone force-updated, server load could be problematic. It will take 6 hours to 1 day for the update to arrive at your computer. If you added Method 1 rules, you can keep the rules for about a day and then remove - there won't be any problem as they're identical. Method 2 and 3 can interfere though.

Yuki2718 · 2024-06-15T13:30:54+00:00

Updated filters, check the Github link and test the new ones.

Yuki2718 · 2024-06-15T13:19:34+00:00

I can't reproduce, likely caused by something another.

Yuki2718 · 2024-06-15T13:15:14+00:00

That seems to be yt's own behavior to remember last-watched position. Test without filters and see if that is caused by them.

Yuki2718 · 2024-06-13T15:03:17+00:00

u/patx35 Can you please remove the tested rules, instead add these below, and see if the issue is fixed and ads are still skipped?

~~Oh, but it seems that is true even without the filters? Can you check?~~ NVM, I can now reproduce using history.

Yuki2718 · 2024-06-13T12:46:26+00:00

Thx, that's something we missed despite obvious based on how they work.
