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 YouTube, Facebook or Twitch report. These sites MUST be reported by clicking their respective links.
• This is not a support issue or a question. For 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.

Plenty of connections blocked. Turn cosmetic filtering back on?

[gorhill]

ignoreGenericCosmeticFilters: true
no-cosmetic-filtering: true

Too many customizations, you will have to diagnose this on your side -- the idea is that if you are willing to heavily customize uBO, then you have to be willing to deal with the consequences.

Here is for issues with uBO itself, filtering issues have to be reported as https://github.com/uBlockOrigin/uAssets through the chat icon in the popup panel, and only for issues which are not the result of customizations.

[gorhill]

And please mind what is asked from you in the prerequisite steps next time:

• 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
  ...
• uBO uses default lists and settings.

[eitimiyabi]

All I know is that you have not installed and tested Chrome 131.

[gorhill]

There are 10 cosmetic filters for pixiv.net in "EasyList", and 15 cosmetic filters for pixiv.net in "uBlock filters – Ads".

You disabled cosmetic filtering.
