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! Note: Some features of the Chrome extension are unavailable on certain Google pages and on web pages that were open before this tool was installed. ## v1.6.3 - Update notices are no longer shown automatically; a badge on the header button now indicates an unread update, and clicking it opens the notice. - Swapped the order of the Sort and Divide buttons. ## v1.6.2 - Fixed the "Force URL Hash Change" option not applying to anchor links added to the page after it finished loading. - Fixed auto-avoid-duplicates not focusing the target window when switching away from a duplicate tab. ## v1.6.1 - Added an "Include tabs in tab groups" option (on by default) to exclude tabs currently in a tab group from duplicate detection, gathering, and auto-avoid-duplicates. - Reloading all windows now shows the number of tabs that will be reloaded and requires an extra confirmation once the count exceeds a safety threshold. - Removed the fixed min/max bounds on the categorize threshold field; negative values are now normalized instead of being clamped. - Fixed a dialog occasionally being canceled immediately after it was opened right after closing another dialog. - Minor visual adjustments to the categorize dialog and popup icons. ## v1.6.0 - Added a "Gather specific tabs into a window" command: pick an open origin (including special pages like `about:blank`/`data:`, grouped by protocol) from the current window or all windows, then gather its tabs into the current window, the current window as a new tab group, or a new window. - The first time you open the popup after this update, a one-time notice introduces the new gather command. - New installs now start with two example Advanced Path Rules preconfigured, for `google.com` (ignoring query except `q`) and `youtube.com` (ignoring query except `v`). - Swapped the order of the Combine and Sort buttons in the popup. ## v1.5.9 - Dialogs (confirm/choices/range) can now be dismissed with a backdrop click, resolving as canceled instead of leaving the action hanging indefinitely. - Fixed Escape closing the extension popup itself instead of just the open dialog. ## v1.5.8 - Duplicates list: added a "Last Accessed" column showing each tab's last-viewed time as a relative duration (seconds/minutes/hours/days). - Added a "By last viewed" sort option to order duplicate tabs by last-accessed time, oldest first. - Clarified the Japanese sort labels ("URL順"/"ページ名順") to avoid implying priority ordering. - Advanced Path Rule: the Origin field now prioritizes the current tab's origin at the top of the suggestion list. - Bumped `minimum_chrome_version` to 121, the minimum version exposing `lastAccessed`. - Fixed the "categorize by hostname" dialog crashing on open in Japanese, caused by an intentionally empty ja translation being misread as a missing one. ## v1.5.7 - Duplicates list: added a button to close a tab directly from the list, without needing to switch to it first. - Duplicates list: fixed the "already closed" status message not being shown due to a missing translation key. ## v1.5.6 - Advanced Path Rule: added an allowlist of query parameters (`allowedQueryParams`) that survive the "ignore query" setting, so params like video/page IDs can be kept even while tracking params are dropped. - Fixed the advanced path rule section heading and Add button labels not being localized. - Fixed a case where the auto-avoid-duplicates feature could close a newly opened background tab (e.g. middle-click/Ctrl+click) without switching back to the existing tab, if the user activated the new tab while it was still being processed. ## v1.5.5 - Advanced Path Rule: the Origin field now remembers recently entered origins and offers them as recoverable datalist suggestions, so an accidental overwrite of a previously entered value can be restored. - Fixed the duplicates list's sticky table header being hidden behind row content while scrolling. ## v1.5.4 - The Danger Zone and Advanced Path Rules sections now animate open/close with a smooth transition instead of snapping instantly. - Buttons, labels, and section headers now brighten on hover instead of dimming, and the hover effect now also applies to labels. ## v1.5.3 - Advanced Path Rule: the Origin/Host field now suggests the current tab's origin as a placeholder and dropdown option, making it faster to add a rule for the site you're on. - Fixed settings that failed to save from silently reverting later; save failures are now surfaced with an alert and the UI is rolled back to the last saved value immediately. - Improved internal code quality: added automated lint/format checks before each commit and expanded test coverage. ## v1.5.2 - Improved browser UI language support for locale variants such as `ja-JP`, so the extension now better matches Japanese UI settings. - Improved internal code organization for better reliability and easier future updates. ## v1.5.1 - Fixed the document language attribute not matching the browser's UI language, which could affect accessibility/screen readers. ## v1.5.0 - Added advanced path rule settings: you can now override the duplicate-matching rule (ignore pathname / query / hash) per origin (scheme + host + port), instead of only a single global Default setting. - Fixed a case where a saved per-origin rule could silently fail to match if the origin was entered without a scheme. - Fixed the advanced path rule row's screen-reader labels being Japanese-only regardless of the browser's language. ## 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
