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.
