adblock-rust VS brave-browser

Brave has written their own (open source) adblock engine (in rust) that is directly integrated into the browser (ie. not an extension, so is not affected by Manifest V3).

https://github.com/brave/adblock-rust

Here is a (somewhat dated) article describing it by the authors:

https://brave.com/improved-ad-blocker-performance/

Brave has its own Rust implementation of an adblocker embedded in the browser: https://github.com/brave/adblock-rust; so it does not embed uBlock Origin (but the filters are mostly compatible)

Disclaimer: I work at Brave but not on the browser.

We support :has currently, which impacts many filters in EL and uBO. Some non-supported filters such as upward() can be manually converted over to use :has instead. The other unsupported procedual filters are a WIP will depend how easy/hard they are implement. No ETA, but have opened a ticket https://github.com/brave/adblock-rust/issues/293

ublock on chromium and brave itself can't use all of the filters in that list: https://github.com/brave/adblock-rust/issues/4

It's open source https://github.com/brave/adblock-rust

I've fixed this in the adblock engine as of https://github.com/brave/adblock-rust/commit/8a755bdb190bb55a3a3acee1e6507085051bdeec, and I'll push to get this patched in 1.47 soon. Thanks for the reports!

You'll notice the actual patching itself is introduced with the caveat:

Brave browser, which blocks ads and trackers, grew to over 50 million monthly active users in 2023 while enabling privacy-first models to counter Google's search and Chrome browser ecosystem.

Still waiting on the Brave stable release with the patched version of chromium https://github.com/brave/brave-browser/issues/35013

Manually download the standalone version from: https://github.com/brave/brave-browser/releases/tag/v1.61.101 and update it that way.

Upgraded Chromium to 120.0.6099.71. (#34740) (Changelog for 120.0.6099.71)

For those looking for a fix: Use the latest Nightly Build for Brave.
