Close Duplicate Tabs

Close duplicate tabs by URL, ignoring query parameters for configured prefixes.

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.
