Advanced Tab Manager

Comprehensive tab management: close duplicates, star favorites, set reminders, and organize your tabs

Duplicate Tab Closer helps you keep your browser organized by intelligently detecting and closing duplicate tabs across all your Chrome windows. The extension uses smart URL matching that ignores query parameters and fragments, so it can identify duplicates even when URLs aren't exactly identical. When duplicates are found, the extension keeps the most recent (rightmost) tab and closes all earlier duplicates. Simply click the extension icon or use the keyboard shortcut (Ctrl+Shift+D on Windows/Linux, Cmd+Shift+D on Mac) to clean up your tabs instantly. KEY FEATURES: • Smart URL normalization treats similar URLs as duplicates • Works across all Chrome windows simultaneously • Visual feedback shows how many tabs were closed • Customizable keyboard shortcut for quick access • Completely privacy-focused with local processing only
