CHROME EXTENSION · MANIFEST V3
Block ads before they load.
Simple Ad Blocker stops ad and tracker requests at the network level, before a single pixel or script reaches your browser. No data collected, no bloat, one toggle.
v1.0.0 — unpacked developer build, not yet on the Chrome Web Store
What gets stopped at the door

How it works
Simple Ad Blocker uses Chrome's built-in declarativeNetRequest API. There's no content script rewriting pages and no third-party filter list fetched over the network — the rules ship inside the extension.
A page starts loading
Chrome begins requesting the scripts, images, and frames a page needs — including calls out to ad and tracking domains.
Each request is checked first
Before a request leaves your browser, Chrome checks it against Simple Ad Blocker's rule list, entirely on your device.
Matches are dropped silently
Requests to known ad and tracker domains are cancelled. No placeholder box, no error in the console — the space simply doesn't load.
Everything else loads as normal
The rest of the page — its own content, images, and functionality — is left completely untouched.
Nothing leaves your browser
Ad blockers ask for broad permissions, so it's fair to ask what they do with them. Here's the whole answer.
- —All filtering happens locally, using Chrome's own request matcher.
- —Simple Ad Blocker doesn't phone home, fetch remote lists, or send usage data anywhere.
- —The blocked-request count in the popup is stored only on your machine.
- —The full source is a few short files — manifest, rules, and two small scripts.
Install it
Simple Ad Blocker isn't listed on the Chrome Web Store yet, so it installs the way any developer extension does — takes about a minute.
