Show HN: Adblock-rust Manager – Firefox extension to enable the Brave ad blocker

https://github.com/electricant/adblock-rust-manager

9•electricant•1h ago

Firefox 149 ships adblock-rust (Brave's Rust engine, MPL-2.0) completely disabled with no UI. It's controlled by two about:config prefs with no WebExtension API, so you can't touch them programmatically from a standard extension.

This extension gives it a UI: ETP toggle (via browser.privacy API, instant), filter list manager with clipboard helpers for the manual about:config steps, and 8 preset lists. You can also add your own if you so desire.

Don't want it. Tracker/Ad blocking should forever be an extension, maintained by someone with zero obligation to, or association with, the ad/tracking industry. A USER agent.

The lists are maintained same as extensions.

> Disable Firefox's built-in Enhanced Tracking Protection so adblock-rust handles blocking instead.

What concrete and practical differences are there between the two? I'm guessing because this exists, adblock-rust somehow is better than the built-in ETP? In what way?

I'm using ETP + uBlock Origin right now, and can't remember the last time I saw an ad, if I used this instead, what practical differences would I notice?

I've been using ETP plus adblock-rs in Waterfox for 2 weeks. I don't see much a difference compared to ETP + ublock origin apart from some cosmetic filtering. The fact that it's not an extension supposedly allows to block at more layers so it's theoretically better than an extension (https://github.com/BrowserWorks/waterfox/issues/4182)

Note that there are (were?) also some small bugs in the waterfox integration (such as the configuration options sometimes disappearing).

Cool project but I have to ask. Why not use brave?

You might want to not use chromium?

Can this extension effectively block ads on YouTube? When I manually enabled the Rust ad blocker in about:config and added filter lists there, ads still appeared on YouTube and some porn sites. While uBlock Origin blocks everything.
