ZenBlock

ZenBlock keeps your browsing calm, fast, and private. Tired of crowded pages, autoplaying videos, and being followed by trackers? ZenBlock removes the clutter so you can focus. It works silently in the background using the same community-maintained filter rules trusted by millions, and it lets you stay in control with per-site whitelists and your own custom filter lists. WHAT IT DOES - Blocks ads, pop-ups, banners, and video ads across the web - Stops trackers and analytics scripts from following you - Blocks advertising and tracking domains at the network level before they load a single byte, which saves bandwidth and speeds up page loads - Keeps everything private: all settings and statistics stay on your device WHY ZENBLOCK - Effective by default: ships with the EasyList ruleset enabled so protection starts the moment you install it - Real, honest statistics: the Dashboard shows the requests actually blocked by the extension; nothing is simulated - Whitelist trusted sites in one click - Add your own filter lists (e.g., regional or custom community lists) right from the options page - Automatic filter updates every 7 days by default (configurable) - Beautiful light and dark themes that follow your preference - Small, fast, and battery-friendly: built on Chrome's native Declarative Net Request engine, so no heavy JavaScript runs on the pages you visit PRIVACY FIRST - No accounts, no sign-ups, no tracking of your browsing habits - Nothing you block is ever uploaded anywhere - Filter lists are fetched from well-known public sources (EasyList) over HTTPS - All data is stored locally in your browser using Chrome's extension storage - The extension never collects, sells, or shares personal information HOW IT WORKS ZenBlock installs its filter rules through Chrome's Declarative Net Request API. When you visit a page, Chrome evaluates those rules before any network data is loaded, so ads and trackers are stopped at the source. Matching can display the number of requests ZenBlock has blocked for you, right on the Dashboard. WHAT ABOUT MY FAVORITE SITES? Some sites rely on ads to stay free. If a page breaks or you simply want to support a site, add it to your whitelist. ZenBlock will leave that site untouched while keeping the rest of your browsing protected.
