Zenith AdBlocker — Ad Blocker & Privacy Guard

Block ads, trackers, fingerprinting, miners & cookie pop-ups with per-site control. 100% local — nothing leaves your browser.

Zenith AdBlocker is a privacy-first ad and tracker blocker for Chrome (Manifest V3). It blocks ads and trackers at the network level, hides leftover ad elements on the page, and gives you per-site control — all processed locally on your device. No account, no telemetry, no data leaves your browser. WHAT IT BLOCKS - Ads — banner, display, native and video ad requests, using Chrome's declarativeNetRequest engine - Trackers & analytics — known tracking and analytics domains, plus smart tracker learning that flags third parties seen across many sites - Fingerprinting — reduces canvas, WebGL and navigator-based fingerprinting on the main page, and sends the Do Not Track and Global Privacy Control signals - Crypto-miners — blocks known browser-based mining scripts - Cookie pop-ups — automatically rejects or hides common consent banners - Annoyances — newsletter pop-ups, floating widgets, app banners and overlays CONTROL - Per-site settings — turn protection, ads, cosmetic filtering, trackers, fingerprinting, cookies, annoyances or miners on or off for any website - One-click Allow — whitelist a site you want to support, without turning Zenith off everywhere - Element picker — right-click anything and hide it - Filter lists — enable or disable EasyList, EasyPrivacy, Peter Lowe's list and optional extended lists from the dashboard PRIVACY - Everything runs locally. Zenith does not sell data, does not send the pages you visit to any server, and has no analytics or remote tracking. - Your settings, allowlist and blocked-activity stats are stored only on your device. - Filter lists are downloaded as plain text from trusted sources over HTTPS and are treated as data, never executed as code. INSIGHT - A live Blocked activity page shows blocked requests in real time, with type and search filters. - A dashboard summarises what's been blocked — counts, top blocked domains and categories — and lets you manage lists and allowed sites. - All of this is counted and shown on your device. Nothing about your browsing is uploaded. Zenith is an independent, open-source project (GPLv3). It is a newer, MV3-focused blocker and does not yet support the full advanced filter syntax of long-established tools. Made by roshanxcvi & Viraj Prajapati.
