T-Dog's AdBlocker

Lightweight, dependency-free ad & tracker blocker by Nelson Agentic. Native declarativeNetRequest, zero per-request JavaScript.

T-Dog Says: Block ads and trackers automatically — with zero bloat. T-Dog's AdBlocker is an ultra-lightweight ad & tracker blocker built entirely on Chrome's native declarativeNetRequest engine. There's no injected JavaScript, no libraries, no build step, and no per-request overhead — blocking rules are matched natively in the browser's own network stack. KEY FEATURES • 330,000+ blocked domains, auto-updated daily — our curated list merged with the trusted OISD Big blocklist, refreshed once a day (or on demand with one click), so new ad and tracker networks get blocked without waiting on a store update. • Native, zero-overhead blocking — every rule runs through Chrome's own declarativeNetRequest C++ network stack. No content scripts, no per-request JavaScript, no slowdown on the pages you visit. • Trusted sites — if blocking ever breaks something (like "Log in with Facebook" on a checkout page), hit Trust site to exempt that one domain instantly, without pausing protection anywhere else. One click to undo. • Manual domain blocking — add any annoying domain from the popup and remove it with one click. • Popup & popunder ad network coverage — the blocklist includes major popunder, redirect, and push-notification ad networks. • Per-tab blocked counter — see exactly how many ads and trackers were blocked on the page you're viewing, right in the toolbar and popup. • One-click pause — a single toggle disables blocking instantly if you ever need to. PRIVACY BY DESIGN T-Dog's AdBlocker requests no host permissions at all. It cannot read or modify the content of any page you visit. The daily blocklist update fetches a static domain list from a CORS-enabled GitHub URL — no browsing data, page content, or personal information is ever collected, read, or transmitted. CREDITS The auto-updating blocklist merges a curated Nelson Agentic list with OISD Big (oisd.nl), a comprehensive, low false-positive blocklist used under its free-use terms.
