About this extension
AdOff is a privacy-focused content filter built from scratch with Manifest V3. It provides a faster, cleaner, and more private browsing experience — instantly, invisibly, and without slowing down your browser.
HOW IT WORKS
AdOff uses three independent layers of protection:
• Network Filtering — Intercepts unwanted network requests before they load, using the browser's native declarativeNetRequest API. 100+ static rules cover known tracking domains, intrusive scripts, and unwanted content delivery networks. Zero background overhead.
• Cosmetic Filtering — Hides intrusive page elements such as banners, pop-ups, cookie walls, overlay content, and video interruptions using precise CSS selectors and smart DOM scanning.
• Stealth Mode (Pro) — Advanced anti-detection technology. AdOff stays invisible to scripts that try to detect content filters, so you never see "please disable your content filter" messages.
KEY FEATURES
• Works on every website — no configuration, no lists to manage
• Ultra-lightweight: only 74 KB — 20x lighter than alternatives
• Per-site control: pause protection with 4 flexible options
• Video ad skipper: automatically handles video interruptions
• Multi-language: English, Italian, German, French, Spanish, Portuguese
PRIVACY FIRST
• No data collection — nothing is tracked, nothing is sent
• No analytics — no third-party SDKs, no tracking scripts
• No external connections — everything runs locally on your device
Your data never leaves your device.
