Close duplicate tab

Close duplicate tab on current window.

At work, I get a lot of notifications from GitHub, Redmine, Backlog, and so on. If you keep opening them in a new tab to read them later, you will have too many tabs in no time. This Extension allows you to organize them in an instant and reload the remaining tabs to make them up-to-date! * Chrome Extension does not work on some Google pages and on opened web pages before installing this tool. Please reload the page you want to use this tool once after installation. ## v1.4.1 - No functional changes. Internal code restructuring (popup module split, centralized type guards). ## v1.4.0 - Added a duplicate count badge on the extension icon, with selectable modes (off / count across all windows / count in the current window). ## v1.3.0 - Added an option to automatically close new duplicate tabs the moment they are opened. - Fixed cases where URL normalization options (such as "ignore hash") were not being applied when closing duplicate tabs. - Duplicates list: fixed a crash that could occur when opening the list, and hardened the list against special characters in tab titles. - Fixed a bug that could steal focus from a background window when a duplicate tab was closed. - Fixed the categorize-range number input so that clearing it no longer breaks the setting. - The "Open tab" button label in the duplicates list is now localized (previously Japanese-only). ## v1.2.4 - No functional changes. Internal build tooling and development workflow modernized (npm, esbuild, stricter TypeScript, tests, CI). - Requires Chrome 120 or later. ## v1.2.3 - When targeting all windows, modified to prioritize closing tabs that are not in the current window. ## v1.2.2 - Improved the tab closing logic to handle duplicates correctly. ## v1.2.1 - Rollback to 1.1.0 ## v1.2.0 - "Close duplicate tabs" button now allows users to review a list of duplicate tabs before closing them. ## v1.1.0 - Added a flag to forcibly update the URL when clicking on intra-page links, such as those in the table of contents. ## v1.0.3 - Update English - Change to use dialog on all task button - Fix confirm dialog bugs ## v1.0.2 - Update function "Divide all tabs for each hostname" - Option added to group tabs into the same window according to the number of sheets when there are only a few tabs with the same hostname. ## v1.0.1 - Fix critical bug that is not able to load savedata ## v1.0.0 - Stable release
