DNS Prefetching — Open Links Faster in Chrome (2026)

SuperchargePerformance scans links on the current page and injects connection hints for the domains those links point to. Every time you navigate to a domain you haven’t visited recently, Chrome performs a DNS lookup before it can start the connection. Resolving that lookup is one of the first steps before any content loads, and on slower connections it sits at the head of the delay chain.

How It Works

The top three domains get a <link rel="preconnect"> hint. Chrome completes the full DNS + TCP + TLS handshake in the background. Remaining domains get a lighter <link rel="dns-prefetch"> hint that resolves only the DNS record.

Click a link to one of those domains and the DNS step is already done. The browser can start the connection and request immediately.

Two Modes

Common mode is lighter — the hint list never changes per page. All is more aggressive, scanning the actual page contents so prefetches cover the specific external services this page links to. The trade-off is more background DNS queries.

Default is Off. Enable it if you find navigation to new domains feels sluggish, particularly on connections with high DNS latency.

PRO Requirement

Predictive DNS Prefetching requires PRO, a one-time purchase rather than a subscription. It is part of PRO alongside custom tab suspension timers, system font forcing, full script blocking, background throttling, and image blocking.

Privacy Note

DNS queries for prefetched domains go to your configured DNS resolver. This means your resolver sees requests for domains linked on the current page, including ones you never click. If that’s a concern, leave the feature off. No data goes to SuperchargeBrowser.
