Firefox integrates an ad-blocker, but not to block ads

Firefox 149 has quietly integrated Brave's Rust-based ad-blocking engine (adblock-rs) into its codebase, but the feature is disabled by default and not intended for consumer ad-blocking purposes. Mozilla appears to be experimenting with the technology for other use cases, while the privacy-focused Waterfox browser fork is actively testing the same engine as a built-in ad-blocker. Users can manuall
