Describe the issue

When I click on a different time in some videos it says an error has occurred and the video stops playing.

Screenshot(s)

Versions

• Browser/version: Firefox 78.0.1 64bit
• uBlock Origin version: 1.27.10

Settings

-Enabled AdGuard Base

Notes

I don't see any setting that would cause any issues with youtube.

Edit: Was a DNS issue for me just FYI.

[liamengland1]

Works fine for me. Does it happen every time, on every video? Does it happen if you restart the browser? If you disable uBo?

[Yuki2718]

I can't reproduce either with Base.

[romulasry]

Works fine for me. Does it happen every time, on every video? Does it happen if you restart the browser? If you disable uBo?

Doesn't happen when I disable uBo.

[romulasry]

Doesn't always happen when I fast forward using the button but when I press right enough it does it.

[Yuki2718]

On my end works fine with whatever position chosen on mouse or whatever times (20+) I press right. Can you reproduce that with public DNS such as Google or CloudFlare? Also can you take screenshot(s) of the logger? Click the button in below pic and reload the page.

[romulasry]

Here is the logger.

I am using the default dns for my ISP Spectrum, it says it is a roadrunner (.rr) IP.

[Yuki2718]

Thx for answering. If you filtered the logger with Blocked and Allowed (see the pic below), is that identical to mine except for their order? If so, I give up.

[krystian3w]

Maybe glitch with the mode to rebuild only a part of the page instead of loading it all over again.

[liamengland1]

As you have been told you before, you need to test without other extensions (no content scripts) #6980 (comment)

[GKid94]

I did and it's the same

[krystian3w]

try:

*/sw.js$script,domain=youtube.com,important

may need clear service worker in devtools:

https://stackoverflow.com/a/41907900

In Google Chrome, you can go to Developer tools (F12) -> Application -> Service worker and unregister the service workers from the list for that specific domain.

---

if no help - delete blockade on /sw.js and try these:

||youtube.com/get_video_info?*=adunit&$important,badfilter

youtube.com,youtube-nocookie.com#@#+js(json-prune, [].playerResponse.adPlacements [].playerResponse.playerAds playerResponse.adPlacements playerResponse.playerAds adPlacements playerAds)

Best test individually, refresh afterwards via Ctrl+F5 - they may also suddenly return pre-roll ads.

[GKid94]

I don't know where to put those codes

[krystian3w]

Into uBO Dashboard in My Filters tab: https://github.com/gorhill/uBlock/wiki/Dashboard:-My-filters

[GKid94]

Oh ok, and what do those codes do

[krystian3w]

Second and third filters they're revoking current methods for blocking pre-roll ads.

The first filter, which seems to be blocking the servivce worker, to partially block the new pre-roll ads (but not all).

[GKid94]

I've added those codes in my filters and it's seems that YouTube is working fine now, they should add that fix in the extension

[krystian3w]

Not so fast!

Find out which of these 3 helps. The blocking of /sw.js is eliminated in the default uBO filters - may break useful functions.
Additionally, Google could disable some A/B test for you, hence the improvement.

[GKid94]

If the first code is disabled then the other two fix the issue, but I think that the last one is the fix and used them the whole day and I didn't see anything broken on YouTube

[GKid94]

@krystian3w I tried all 3 codes separately and the first one works the best, the second and the third one still have issues with YouTube

[Yuki2718]

That sounds conflicting to your previous comment:

[stephenhawk8054]

@aquamacho1 What happens if you turn off uBO?

[aquamacho1]

@stephenhawk8054 i kid you not XD
https://github.com/uBlockOrigin/uAssets/assets/69878708/dda94e9b-0673-4760-92e7-aa389aaa7d87

[stephenhawk8054]

@aquamacho1 Then something else is blocking things on your computer and it's not related to uBO any more.

[aquamacho1]

@stephenhawk8054 well, yes, but not only i needed to uninstall all of the extensions, but also reset google chrome to defaults afterwards, now all looks good.
Now i will test more.

@stephenhawk8054 I apologize for wasting your time man, i feel stupid now.

[Sarm1X]

Hey @stephenhawk8054,
Problem is not solved even after force update of all filter lists at you suggested.
https://github.com/uBlockOrigin/uAssets/assets/17095848/166bb596-e958-4010-a9ed-0b35a354eafd

I would be glad to help solve this annoying shit out.

[stephenhawk8054]

@Sarm1X Are you using any other extensions?

[Sarm1X]

@stephenhawk8054 In what manner?
Of course, I am using another extensions but not related to Ad blocking.
https://github.com/uBlockOrigin/uAssets/assets/17095848/59d8bec3-a7ca-4231-931e-3ba489bc2272

[stephenhawk8054]

@Sarm1X Can you turn off all of them and test again?

For example, enhancer for YouTube has adblock feature.

[Sarm1X]

I have disabled the AdBlock feature in YouTube enhancer, let's see if this fix the issue.
@stephenhawk8054

[Nezumi-chan]

@Nezumi-chan Are you using any other extensions and browser built-in blocker?

Using PrivacyBadger, but turning it off doesn't fix it. Also tried turning off Facebook Container and GroundNews. Also have two Workona extensions, but they shouldn't affect this. Can still try turning them off. Also, already turned off browser tracker blocker for Youtube after it caused this issue before. Even, just on the off chance, tried turning off autoplay blocking. It really does seem to be down to uBlock.

EDIT: Just to be absolutely sure, I turned off the Workona extensions, fully turned off Privacy Badger, and turned off even the duplicate tab closer. Nothing.

[stephenhawk8054]

@Nezumi-chan Can you force update all your filter lists (click uBO icon > ⚙ Dashboard button > "Filter lists" pane > 🕘 Purge all caches > 🔃 Update now) and test again?

[Nezumi-chan]

@stephenhawk8054 Okay, will try that next!

EDIT: No results. If it helps any, I have these custom filters from when it was having a lot of trouble getting around the adblock checker on Youtube:

youtube.com##+js(set, yt.config_.openPopupConfig.supportedPopups.adBlockMessageViewModel, false)

youtube.com##+js(set, Object.prototype.adBlocksFound, 0)

youtube.com##+js(set, ytplayer.config.args.raw_player_response.adPlacements, [])

youtube.com##+js(set, Object.prototype.hasAllowedInstreamAd, true)

[Nezumi-chan]

Realized that editing with the results might not have been the best way to get a response. So... yeah. Sorry!

[stephenhawk8054]

@Nezumi-chan Please remove your custom filters as well. Those filters are useless.

[stephenhawk8054]

Everyone, please don't auto-assume that an extension is unrelated to adblock/YouTube. We, and you, don't know how each extension works and how it affects YouTube.

Currently there are more than 1 method YouTube is using for anti-adblock, and it can be caused by other extensions (older methods) or it can be caused by their latest methods.

The easiest way for us, and you, to properly investigate the issue is testing while using only uBO.

[Nezumi-chan]

Which is why I eventually disabled all other extensions to be sure. And it's... not helped. Nor did removing the custom filters. Gonna try completely restarting Firefox, with some Youtube tabs open and it set to once again retain old windows and tabs, to see if that changes anything. And then gonna try not retaining old windows and tabs and just opening a new youtube video. Will reply with updates.

[stephenhawk8054]

@Nezumi-chan Yes, I am reminding everyone in general.

I DON'T mean turning off other extensions will auto-fix the issue. What I mean is it's the EASIEST way to properly investigate the cause.

Looks like mine is this,

[stephenhawk8054]

@showierdata9978 Can you force update all your filter lists (click uBO icon > ⚙ Dashboard button > "Filter lists" pane > 🕘 Purge all caches > 🔃 Update now) and test again?

[Nezumi-chan]

@stephenhawk8054 Okay, it came back to where it was (sometimes clicking on a fresh link will generate a correct timestamp for where I left off, but it forgets after a refresh, closing Firefox, etc.) after turning on some of my extensions. So it's either directly or indirectly because of one of them.

[VaelophisNyx]

alright so the popup is no longer an issue, but now I can't element-block anything but thumbnails. Nothing is even capable of being selected?
