About this extension
TabZero is a strict allowlist browser extension.

All websites are blocked by default. When a user visits a website that is not on the allowlist, TabZero shows an internal block page where the user can allow the domain temporarily, allow it permanently, or block it permanently.

All decisions are stored locally in the browser. TabZero does not collect, transmit, or share any personal data. No external services or servers are used.
