3rd party Ad-blocking extensions not working

[Eic]

Short description:
Long story short, I wanted to use ublock for more control over ads showing up (to keep some on and turn some off). Then I noticed that it doesn’t block anything beyond what built-in adblock blocks (even if I explicitly ask it to). And as good as built-in Ad-block is, it still has long way to go to be used as primary software.

Sides and top are clean on Chrome version.
I used this website as an example, some places are even worse.
OS: Ubuntu 16.04.6
Brave Version 0.61.52 Chromium: 73.0.3683.86 (Official Build) (64-bit)
Steps to recreate the issue:

1. Download uBlock (or any other ad-blocking extension (tried with uBlock, AdBlock and one VPN extension that I do not want to advertise)) from chrome web store
2. Visit a website that built-in brave adblock doesn’t clean from ads (above screenshots from tetris.com/play-tetris)

Thanks for reporting the issue. I’ve logged an issue for this

Until its fixed you can actually enable shields and just use the context menu to block specific elements on the page
