Bulk Tab Duplicate Remover

WHAT IT DOES

Bulk Tab Duplicate Remover solves a common browser management challenge: duplicate tabs accumulate over time from repeated link clicks, search results, and navigation, cluttering your browser and consuming memory. Most browsers lack a native way to find and close duplicate tabs in bulk. This tool reads the current browser page and scans for duplicate tabs by comparing URLs (normalized by removing trailing slashes and query parameters). It displays a scrollable checklist of all duplicate tab instances grouped by URL, showing tab titles and URLs. You can select which duplicate tabs to close, with options to keep the oldest tab, keep the newest tab, or manually select which tabs to keep. The tool then processes each selected tab, closing it through the browser's tab close interface. A preview shows your selection before closure, and progress tracking shows each tab as it's closed.

WHERE IT RUNS

This extension panel runs directly inside your browser as an overlay on any web page. It works on any site and scans the current page's DOM for tab-like elements. The tool detects tabs from the page's DOM and uses DOM manipulation to close tabs. It requires no additional API keys or permissions beyond the BotGentz extension. The tool works on browser tab management pages, bookmark managers, and any page that lists tabs or links.

HOW TO USE

After installing the BotGentz extension and activating Bulk Tab Duplicate Remover, navigate to a page that displays tabs (such as a tab manager, bookmarks page, or any page with tab-like elements). Click the extension icon in your browser toolbar to open the panel. The tool automatically detects all tab-like elements on the current page and scans for duplicates. Duplicate tabs are grouped by their normalized URL, and each group shows the number of duplicates found. Use the "Keep Oldest" button to select all duplicate tabs except the first in each group, or "Keep Newest" to select all except the last. You can also manually check individual tabs using the checkboxes. The preview section shows how many tabs will be closed. Click "Close Selected Duplicates" to close all selected tabs. The tool processes each tab with a 400ms delay, showing progress as each tab is closed. A notification appears when all tabs have been processed.

TECHNICAL OPERATION — DOM-Based Tab Detection and Closure

This tool scans the page for tab-like elements using selectors like `[data-tab-id]`, `.tab`, `.tab-item`, `[role="tab"]`, and `a[href]`. It extracts tab titles, URLs, and close buttons from each element. URLs are normalized by removing trailing slashes and query parameters to identify duplicates accurately. Tabs are grouped by their normalized URL, and each group displays all duplicate instances. When closing a tab, the tool attempts to click the close button if available; if not, it removes the element from the DOM. A 400ms delay between closures prevents UI congestion and ensures each operation completes. The tool supports grouping by domain for broader duplicate detection, and offers quick selection options to keep the oldest or newest tab in each group. Results can be exported as CSV or JSON for record keeping.

THE PANEL

The extension panel is fully draggable and remembers its position per site session. It snaps to the nearest edge of the browser viewport when dragged within 50 pixels of any side. You can collapse the panel to a compact title bar using the minimize button, preserving your selection state. The panel resizes vertically by dragging the bottom edge. Press the Escape key to close the panel instantly without losing your selection. The preview updates in real-time as you select or deselect tabs.

PLEASE NOTE

This tool requires the free BotGentz extension to function. The script operates by detecting tab-like elements on the current page and closing them via DOM manipulation. It does not use the browser's tabs API and cannot access tabs outside the currently visible page. The tool only sees elements that are rendered in the page's DOM. Tab detection depends on the page's structure and may not work on all tab management interfaces. The tool does not store, transmit, or log any tab data, URLs, or user activity. All operations occur locally in your browser session. Closed tabs are removed from the page's DOM — ensure you review the preview before confirming closure. Export formats include CSV and JSON for maximum compatibility with analysis tools.
