adblock-rust

Brave has its own ad blocker engine built-in rather than as an extension, and it can reuse uBlock's lists https://github.com/brave/adblock-rust I use brave on my phone and I can't really tell the difference from desktop browser+UO, so I guess it works well enough.

Got it. For ad-blocking, we are already working on integrating Adblock-rust, should be available soon! https://github.com/brave/adblock-rust

Though his brave is a relatively small company, they have enough resources to have developed, and continue maintaining their own low-level ad blocker, which IME has been just as effective as uBO, but is supposedly more efficient (since it's written in the R-word language and compiled into native code integrating deeply inside the browser): I can't imagine what hoops Google would have to jump through to block third parties from integrating their own ad blockers. You don't need MV2 for that AFAIK. https://github.com/brave/adblock-rust

Everytime news like this comes up, I'm never affected. I'm using uBlock Origin. Is there something unique about uBlock Origin? Are other adblockers easily noticed by YouTube? TFA mentions complaints from users of Brave browser, which appears to use it's own bespoke ad-blocker [0]. It includes some filters from uBlock Origin [1], but these files are six years old. Are those filters updated at runtime (e.g. from [2], [3], [4], [5])? If so, then why include old filters in the repo? Surely, Brave isn't using six year old filters.

> install uBlock Origin in Brave There's no need to do it, their built-in adblocker supports the same rule lists. https://github.com/brave/adblock-rust

Brave and Vivaldi will continue to support it for some time. Brave also does not really depend on MV2 as they have their own adblocker (which is about as effective as uBO, I believe). edit: link to their adblocker: https://github.com/brave/adblock-rust

If you really wanted to know, most of the tests for Brave's adblock engine are at https://github.com/brave/adblock-rust/tree/master/tests Those are automated unit and integration tests with controlled filter data as inputs. That's the only practically useful kind of test for an adblocker.

Why do you think this would happen? Brave incorporates ublock as part of their Rust based adblocking library https://github.com/brave/adblock-rust

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's adblocker is written in Rust [0] and compiled to native code; it's not affected by the Mv3 transition because it doesn't use extension APIs. Brave also publicly committed [1] to continuing support for Mv2 through patches. [0] https://github.com/brave/adblock-rust [1] https://twitter.com/brave/status/1574822799700541446

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.

There is a solution for Chromium based browsers: https://github.com/brave/adblock-rust but you will only have it built-in in Brave currently.
