Adblock Custom Filters Do Not Work

[Jozer99]

Description

Adblock custom filters on about:adblock do not work. This bug seems to have been reported and closed multiple times before but still exists.

Steps to Reproduce

Simple example:

1. Go to website www.nytimes.com
2. Verify that NY Times logo image is contained in div class "nyt-logo"
3. Go to about:adblock and scroll to custom filters
4. Create custom filter "##.nyt-logo"
5. Refresh www.nytimes.com

Actual result:
The NY Times logo is still visible.

Expected result:
The NY Times logo should have disappeared from the NY Times page. Note that this is just an example, I don't actually want to block the NY Times logo. Tested on Chrome with uBlock Origin and got the correct behavior.

Reproduces how often:
100% of the custom filters I have tried have zero effect, including simple ones such as the example described above.

I confirm this on Mac.

I want to block the annoying ads at the end of a youtube video by adding this rule

www.youtube.com##.ytp-ce-element

but it doesn't work

Is this issue ever going to be addressed? For a browser that advertises its privacy features, having a non-functional content blocker seems like a big deal.

Confirming this on Win 10 x64, Brave v0.21.18 (rev 580be78; current live release as of 15.03.2018).

Custom filters in about:adblock do not work.

Steps to Reproduce

1. Go to Spotify web player with shields up.
   1. Click "Play" on any music playlist/collection.
   2. Verify that there will be no audio playback/streaming.
2. Go to about:adblock.
   1. Add @@audio-fa.scdn.co custom filter.

Actual result:

As the host audio-fa.scdn.co still gets blocked, audio playback/streaming is not possible with shields up.

Expected result:

The custom adblock filter @@audio-fa.scdn.co (and/or @@scdn.co/audio) should allow audio streaming from Spotify's CDN.

Additional Information

• Another open issue related to custom adblock filters: adblock regional and custom filters don't seem to work #6243.
• Open issue related to Spotify audio playback: Spotify player widget doesn't work.  #4053.

As I also think this is a rather big deal, taking the liberty to /cc @lukemulks. Thanks.

Why was this moved to Triage Backlog? I am afraid it will take years to fix this if this is not prioritised. There must be a way to add custom ad-block filters, especially now, when Brave native ad-block is not efficient enough and ignores many ads and keeps them displayed.
Please reconsider the priority for this issue, because even an ad-block chrome extension gives their users the opportunity to add custom filters. If an extension can do this, why a whole browser focused on ad-blocking can't ?

If this functionality doesn't work, please remove the custom filter from the about:adblock page.

This just wastes peoples time, trying to figure out why it isn't working...

@bbondy @kjozwiak @srirambv @LaurenWags does the custom filter functionality work?

Custom element filters (###hot-network-question for Stack Exchange) do not seem to work for me. I'm using Brave 0.23.39, macOS 10.14 Beta
