Close Duplicate Tabs

MAJOR UPDATE: Now with automatic tab grouping & automatic duplicate tab closing! Check options to enable settings!

Too many duplicate tabs can quietly slow down your browsing and make it harder to stay organized. Close Duplicate Tabs helps you spot duplicate tabs quickly and clean them up in one click.

Use the popup to review duplicates before closing them, or turn on automatic duplicate cleanup for a more hands-off workflow. The extension also supports a keyboard shortcut, tab-count hover summaries, optional automatic tab grouping, URL matching controls for # fragments and ? query strings, and an exclusion list for domains you do not want to deduplicate.

Key features:

- One-click duplicate cleanup
- Optional auto-close for new duplicates
- Popup review with per-URL manual close
- Keyboard shortcut for closing all duplicates
- Hover summary with tab count and duplicate count
- Optional smart tab grouping by domain
- Matching controls for # fragments and ? query strings
- Exclusion list for domains to ignore
- No data collection

Keyboard shortcut: Ctrl + Shift + X / Cmd + Shift + X
