Duplicate Tab Cleaner - Find & Close

Instantly find, highlight, and close duplicate tabs across windows and tab groups. Safe URL matching with zero aggressive redirects.

Too many tabs open, and half of them are the same page? Duplicate Tab Cleaner finds every repeated tab across all your windows and closes the extras in one click. It is built to be safe and simple. Nothing is ever closed automatically, and anything you close can be brought back with Undo. HOW IT WORKS 1. Click the toolbar icon. The badge already shows how many duplicates you have. 2. Look at the list. Each page shows which copy will be kept and which will be closed. 3. Press "Close All Duplicates". Done. FEATURES • One click, no setup. The defaults work well for most people. • Never closes tabs on its own, so sign-in pages, documents and work tools are not interrupted. • Undo. Closed tabs come back in the same window, position and tab group. • You stay in control. Pick a different copy to keep, or close a single tab with the ✕ button. • Works across all windows, or only the window you are using. • Respects Chrome tab groups. Group names and colours are shown, and your groups are not broken up. • Pinned tabs are protected and never closed. • Smart matching. The same page with tracking codes (utm_source, fbclid and similar) or a different #section still counts as a duplicate, while web apps that use #/ addresses are kept separate. • Search the list by site or page title. • Keyboard shortcuts: Alt+Shift+D opens the list, Ctrl+Shift+X (Command+Shift+X on Mac) closes all duplicates right away. • Follows your light or dark theme. • Available in English, Spanish, German and Simplified Chinese. FOR DEVELOPERS • localhost, 127.0.0.1 and private network addresses are skipped by default. • Add your own "never touch" list using plain text, wildcards (staging.*) or regular expressions. • Four matching levels, from exact address to ignoring the query string. PRIVACY • Works fully offline. • No accounts, no analytics, no ads, no tracking. • Your tabs and browsing history never leave your browser. • Only three permissions: tabs (to find duplicates), tab groups (to show and preserve them) and storage (to remember your settings).
