Ad Blocker — Block Ads and Trackers in Chrome

Ad Blocking stops ads, trackers, analytics scripts, and malware domains before they load — using rules that are bundled directly inside the extension. Pages render faster, bandwidth is conserved, and you are not tracked across sites as you browse. All three blocking levels are free; no subscription is required.

How It Works

SuperchargePerformance uses Chrome’s declarativeNetRequest (DNR) API to evaluate network requests against a set of static rules before they leave your browser. When a request matches a blocked rule, Chrome drops it at the network layer — the page never receives a response from the blocked domain.

The rules are split across 14 static rule files bundled with the extension, covering ad networks, trackers, analytics endpoints, and malware/phishing domains at increasing coverage levels. Because all rules ship with the extension, there is no startup network request to fetch remote filter lists. Rule updates arrive with normal extension version updates through the Chrome Web Store.

Settings

The default is High (level 3). This is the recommended setting for most users and provides the broadest protection without requiring any configuration.

When to Use This

• You want faster, cleaner page loads without installing a separate ad blocker extension
• You are consolidating extensions and want ad blocking bundled with performance tools
• You browse on a metered or slow connection and want to reduce wasted bandwidth
• You want malware and phishing domain blocking without additional software

If you already use a dedicated ad blocker, you can set this feature to Off or Low to avoid rule overlap.

Privacy

All blocking decisions happen locally using rules embedded in the extension. No visited URLs, blocked request data, or browsing history is transmitted anywhere. The extension has no analytics, no telemetry, and no remote logging.
