  description

  Too many duplicate tabs from notifications and repeated links?
  Close Duplicate Tabs helps you clean up in one click.
  
  How it works:
  
  Click the extension icon to detect duplicate tabs across all windows.
  The extension keeps the latest tab (highest tab ID) and closes older duplicates.
  For selected URL prefixes, query parameters can be ignored so similar links are treated as the same tab.
  Features:
  
  One-click duplicate cleanup
  Real-time badge count on the toolbar icon
  Rule-based “Ignore Query” matching by URL prefix
  Fast and lightweight (no external services)
  Example:
  
  Rule: https://www.example.com
  These can be treated as duplicates:
  https://www.example.com/
  https://www.example.com/?a=10
  https://www.example.com/?a=10&b=20
  Use it to keep your browser focused and your tab bar under control.

  Close Duplicate Tabs
  
  Clean up duplicate tabs instantly — across all windows, with full control over what gets closed.
  
  How it works
  
  Click the extension icon to open a live preview of all duplicate groups. Review which tabs will be kept, close individual duplicates or entire groups, then undo if needed.
  
  Features
  
  Visual popup — see duplicates grouped by URL before closing anything
  One-click close all, or close group by group
  Undo — reopen tabs you just closed
  Smart keep strategy — keep the most recently accessed, oldest, newest, pinned, or current-window tab
  Ignore query parameters — treat example.com?a=1 and example.com?b=2 as the same tab using URL prefix rules
  Exclusion list — skip domains you never want deduplicated
  Live Mode — automatically redirect duplicate tabs to the existing one as you browse
  Auto-close mode — silently close duplicates in the background
  Works across all windows, or limit to current window only
  Badge shows duplicate count at a glance
  
  No data collection. No external services.
