Duplicate Tab Remover

Review and close duplicate tabs in the current window.

Find duplicate tabs in the current Chrome window, review the duplicate groups, then choose Remove duplicates to close the listed copies. Duplicate Tab Remover compares http:, https:, and file: URLs while ignoring fragments and known tracking parameters, and preserves meaningful query parameters in their original order. Internal Chrome pages, extension pages, opaque URLs, and tabs still navigating are skipped. It keeps one tab per group, favoring the active tab, then a pinned tab, then the earliest tab. Pages that use URL fragments for in-page navigation or app routes (for example, #inbox and #sent) may be grouped together; review the popup before removal on those sites. URLs with the same query parameters in a different order may remain separate. Before closing popup-reviewed candidates, the extension rechecks that they remain duplicates in the same window and are not active; a simultaneous navigation can still race that check. You can also run duplicate removal directly from the Chrome context menu or the Ctrl+Shift+U shortcut (Command+Shift+U on macOS). The shortcut can be changed in Chrome's extension keyboard-shortcut settings. Tab comparison happens locally in Chrome. The extension makes no network requests and does not send tab information to a server. Permissions: • Tabs — read tab URLs and state to find duplicates in the current window and close duplicate copies. • Context menus — provide Chrome context-menu integration.
