Tab Deduper Extension

Tab Deduper is an extension to find and remove duplicate Chrome tabs.

Unlike other currently available extensions which dedup tabs, Tab Deduper differentiates itself in the following ways:

- Duplicate tabs are not automatically closed. A list of duplicated tabs are presented, allowing for precise control over which tab gets closed.
- Use of text OR regular expression based settings to control how tabs are compared, including use of title, fragment, and doing sed-like regex replacements on URLs. This last feature is very useful if you use other extensions which modify your tab URLs.

Philip T. (ID: 00000012acca8beb) Voted 5 ★ - Updated 11/11/2023 Focus on finding, presenting and managing duplicate tabs only. Allow you to see, click to duplicate tabs (whether in the same or across windows) to confirm before acting. Exactly what one needs: simple and effective.

Vitya Aleksandrov (ID: 000000ca528ceb48) Voted 5 ★ - Updated 08/15/2023 Clean UI. Many other similar extensions close all duplicated tabs with one click, i wanted something with more control. Thanks devs for this simple solution. Love that i can use regex to specify what is an is not duplicated PS. some mentioned it does not work with multiple windows, it does for me. great color coding to identify that duplicated windows are across different instances of chrome.
