uBlock-issues (original) (raw)

Details

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

Generic cosmetic filters don't hide nodes in Shadow DOM. Probably not injected to the page because nodes "in shadow" are not detected.
- Related issue a general filter ###euConsent added easylist/easylist#4232
- This works in ABP/AdBlock, Chrome 78 (Probably because all filters are injected?).
Specific filters works, but are not logged.
- This does not work in ABP/AdBlock.

Steps to Reproduce

"Generic" case:

Add ###euConsent to My filters
Open linked VirusTotal page

"Specific" case:

Add virustotal.com###euConsent to My filters
Open linked VirusTotal page

Expected behavior:

Cookie notice on the bottom should be hidden with generic filter. Filter should be logged.

Actual behavior:

Notice is hidden only by specific filter. No DOM filters are logged.

Your environment

uBlock Origin version: 1.23 on Chrome, 1.24.3b1 on Nightly, 1.24 on 70.0.1 Fx
Browser Name and version:
Operating System and version: Manjaro KDE

@krystian3w, it's side effect of uBO performance/memory optimizations. ABP injects all cosmetic filters unconditionally (AFAIK). uBO injects only specific filters. For generic filters, DOM is scanned and only matching ones are injected. Here Shadow DOM is interfering.
