Duplicate Tab Finder

🔍 Too many tabs open? Duplicate Tab Finder instantly shows you which ones are exact copies and closes them in one click.
If your browser ever slows down, crashes, or just looks like a mess of 50+ tabs, there's a good chance you have duplicate tabs eating up your memory. Duplicate Tab Finder solves that in seconds.

⚡ HOW IT WORKS
Click the extension icon. Instantly see every duplicate tab, color-coded and labeled so it's 100% clear which tab to keep and which ones are wasting your memory. Close one group, close everything, or pick exactly which tab survives - all without opening a single settings menu.

✅ KEY FEATURES
🔴 Visual banner on duplicate tabs - a red warning bar appears directly at the top of every duplicate page in your browser, even without opening the popup. It tells you how many copies are open and lets you close that tab with one click.
🎯 Crystal-clear KEEP / DUPLICATE labels - every tab is marked. Green bar + ✓ KEEP means it stays. Red bar + ✕ DUP means it's a copy. No guessing.
💥 Close All Duplicates in one click - one big button at the top wipes every duplicate at once. Your browser goes from chaos to clean in under a second.
↩️ Undo - accidentally closed something? Restore your last action instantly.
🔎 Smart URL matching - catches duplicates that aren't obviously the same. Treats www.example.com and example.com as identical. Ignores tracking parameters like ?ref=google. Ignores #section links. Fully configurable.
📊 Live stats dashboard - see your total tabs, number of duplicate groups, how many you can close, and how many you've cleaned up today.
🔍 Search and filter - type to find duplicates by site name or page title. Filter by groups with 2, 3+, or 5+ copies.
📋 Export your duplicate report — download a full .txt list of every duplicate group for reference or sharing.
⌨️ Keyboard shortcuts - press / to search, R to refresh the scan, Escape to close settings.
🪟 Multi-window support - scans all open browser windows at once, not just the current one.
⚙️ Flexible settings - choose which tab to keep (oldest, newest, or the one you're currently on). Toggle URL matching rules. Disable or enable banners.
🔒 100% private - no accounts, no tracking, no network requests. Everything runs locally in your browser. Your tab data never leaves your device.
