How to block ads on Android

Why Chrome on Android has no ad blocker extensions

On desktop, ad blockers are browser extensions. But Chrome for Android deliberately doesn't load extensions, so extension-based blockers simply can't run in it. That's a Chrome limitation, not an AdOff one — and it's why "ad blocker for Chrome Android" rarely works the way people expect.

The working way: Firefox for Android + AdOff

Firefox for Android does support add-ons. Install Firefox for Android, open its Add-ons menu, search for AdOff and add it. From then on AdOff blocks ads, trackers and ad slots on your mobile browsing the same way it does on desktop.

This is the genuinely honest path on Android: we're not claiming a Chrome-Android miracle — we're pointing you to the browser where extensions actually run.

What about iPhone and other browsers

On iPhone, Safari supports content blockers but the model is different; AdOff currently focuses on desktop Safari and the Chromium/Firefox families. On Android, sticking with Firefox for Android is the most reliable option today.
