The ad blocker for Mac that keeps your Mac light

How to block ads on a Mac

Install AdOff in your browser on your Mac — Chrome, Firefox or Edge all work — pin it, and most ads disappear on every site immediately. No configuration, no account. Ad blocking happens inside the browser, so it covers every site you visit from macOS without touching system settings.

Network blocking stops ad and tracker requests before they load, and cosmetic filtering hides any ad slots that slip through, so pages render cleaner and with fewer moving parts.

Why a browser extension, not a system-wide app

Ad-blocking apps for macOS insert themselves between your Mac and the network, filtering every connection. A browser extension is more focused: it filters only what the browser loads, where the vast majority of ads actually appear. That means a smaller footprint, nothing to grant system permissions for, and no extra daemon running in the background.

RAM and battery: less loaded, less drained

Ads aren't just annoying — they're weight. Autoplaying video ads, trackers and heavy scripts all cost memory and CPU. By stopping many of those requests before they load, a lightweight blocker like AdOff means your browser has fewer resources to fetch and run. Pages can feel snappier, and on a MacBook that can translate into less battery spent on advertising you never asked for.

Frequently asked questions

Do I need a separate app to block ads on Mac?

No. A browser extension like AdOff covers the sites you visit in Chrome, Firefox or Edge on macOS, without installing anything system-wide.

Does AdOff work on MacBook?

Yes. AdOff runs in desktop browsers on macOS — Chrome, Firefox and Edge — on any Mac, including MacBook Air and MacBook Pro.

Is an ad blocker good for battery life?

It can help. Ads and trackers are extra requests, scripts and often autoplaying video. Blocking many of them before they load reduces the work your browser does, which is one of the reasons pages can load faster with AdOff on.

Is AdOff for Mac free?

Yes. AdOff is 100% free, with all features included: network and cosmetic blocking, video ad neutralization on IMA-based players, and stealth anti-adblock protection.
