Description
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.

Could you build this?
Partial While the browser extension UI is trivial, integrating and controlling internal browser engine preferences and low-level Rust ad-blocking libraries without standard WebExtension APIs requires deep browser-internals knowledge.
What it would actually take: A full solution requires a WebExtension coupled with Firefox about:config policies, native messaging hosts, or custom Firefox distribution scripts. The hard part is circumventing WebExtension sandbox boundaries to interact with internal browser Rust engine components (adblock-rust) without exposing security vulnerabilities. Deep expertise in Mozilla internal APIs, XPCOM/Gecko internals, and native messaging is necessary.
