About this extension
DBlocker is a modern, user-controlled browser extension designed to eliminate intrusive popups, pop-unders, invisible click overlays, auto-redirect traps, and malicious iframes on video streaming, manga, and media sites.
  • 🚫 Comprehensive Popup & Popunder Blocker: Stops aggressive window.open calls and tab-unders in their tracks.
  • 🛡 Click Overlay Neutralizer: Automatically disables invisible overlay layers designed to hijack your first click.
  • 🔄 Programmatic Redirect Defense: Blocks forced navigation via Navigation APIs, Location hooks, cross-origin history tampering, and meta refresh.
  • 🎬 Smart Video Player Protection: Intelligently distinguishes ad iframes from legitimate video players, preserving clean playback.
  • 🔑 TLD-Independent Site Key Protection: Keeps protection active even when streaming sites change domains (e.g., from .com to .xyz or .net).
  • 🎯 Granular Allowlist: Fine-grained permissions separated by type (iframe, popup, redirect, external-link) so allowing a player does not grant popup permissions.
  • 🔒 Zero Data Collection: 100% local processing. No tracking, no external telemetry, and strictly respects your privacy.
