Adblock-rust Manager, a Firefox extension.
Technical Positioning
Provides a UI to enable and manage Firefox's built-in, but disabled, Brave ad blocker (adblock-rust), offering ETP toggle and filter list management.
SaaS Insight & Market Implications
This project highlights a common developer pain point: accessing and controlling hidden or undocumented browser functionalities. By creating a UI for Firefox's disabled `adblock-rust` engine, it unlocks a powerful, built-in capability. For B2B SaaS, this demonstrates the value of tools that expose and manage underlying platform features, particularly for enterprise browser deployments. Organizations often require granular control over browser behavior for security, compliance, or productivity. Solutions that provide a managed interface for such features can streamline IT administration, enhance endpoint security, and customize user experiences within corporate environments, bypassing limitations of standard APIs.

Show HN: Adblock-rust Manager – Firefox extension to enable the Brave ad blocker
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.
Developer Debate & Comments
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.
Cool project but I have to ask. Why not use brave?

> 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?
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.
