Tab Blocker

When enabled, immediately closes any new tab before it loads.

Tab Blocker Tab Blocker is a premium, lightweight Chrome extension designed to permanently eliminate unwanted pop-ups, forced background tabs, and intrusive network ads. Whether you're researching, streaming, or working, Tab Blocker guarantees that your browser only opens the tabs you explicitly ask for. Key Features: Total Tab Control: Instantly destroys any new tabs or windows spawned by websites without your permission. In-Page Overlay Annihilation: Automatically scans and permanently deletes full-screen DOM pop-ups, paywall overlays, and "subscribe now" banners before they block your screen. AdBlock Firewall: Built on Manifest V3's lightning-fast declarativeNetRequest protocol to silently block major ad networks and trackers at the network level. Precision Targeting: Choose to block everything globally, isolate and block only the specific tabs giving you trouble, or enforce strict rules on blacklisted URLs. Intelligent Exemption: Manually opening tabs (like pressing Ctrl+T or clicking links yourself) is always fully protected and allowed. How to Use: Pin the extension to your Chrome toolbar. Click the icon to open the minimal control panel. Select your preferred mode from the dropdown (Block All Tabs, Block This Tab Only, or Block Specific URLs). Click the large toggle button to activate the shield (the UI will turn neon green). Browse uninterrupted. To manage mass-blocked tabs, use the Disable All or Exempt buttons dynamically.
