About this extension

ShieldBlock Ultra is an advanced, undetectable ad and popup blocker engineered specifically for modern media websites, video players, and streaming platforms.

Stealth Ad Defusing: Intercepts dynamic ad reloaders (aclib, ferocitycandour, llvpn, madcash) in real time before popups or redirects can trigger.
Anti-Adblock Detection Evasion: Neutralizes anti-adblock scripts with undetectable surrogate mocking so video streams play seamlessly without detection warnings.
Declarative Network Filtering: Fast, low-memory filtering blocking malicious trackers, banners, and click-jackers.
Custom Whitelisting & Filter Subscriptions: Toggle protection per-site or subscribe to additional custom filter lists with one click.
Privacy First: Operates strictly on-device with zero tracking or telemetry collection.
