Bulk Tab Memory Hog Identifier and Closer

WHAT IT DOES

Bulk Tab Memory Hog Identifier and Closer solves a common browser performance challenge: identifying which tabs are consuming the most memory and closing them to free up system resources is tedious when done manually. Most browsers show memory usage per tab only in their task manager, which requires navigating away from the page. This tool reads the current browser page and detects all visible tab-like elements, extracting their titles and URLs. It then analyzes each tab's content to estimate memory usage based on page complexity — counting DOM elements, images, scripts, iframes, and estimated resource size. Each tab is displayed with a memory usage indicator (Low, Medium, High, or Very High) and a score. You can filter by memory level, select multiple high-memory tabs, and close them all at once. A preview shows selected tabs before closing, and progress tracking shows each closure as it completes.

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 analyzes their content to estimate memory usage. It requires no additional API keys or permissions beyond the BotGentz extension.

HOW TO USE

After installing the BotGentz extension and activating Bulk Tab Memory Hog Identifier and Closer, 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 analyzes each one to estimate memory usage. Each tab appears with its title, memory score, and level indicator: green for Low, yellow for Medium, orange for High, and red for Very High. Use the filter dropdown to show only tabs of a specific memory level. Check the boxes for the tabs you want to close. The preview section shows how many tabs are selected and the estimated memory savings. Click "Close Selected Tabs" to close all selected tabs. The tool processes each tab with a 300ms delay, showing progress as each tab is closed. Click "Export Report" to copy a report of all tab memory usage data to your clipboard in CSV or JSON format. Click "Refresh" to rescan the page.

TECHNICAL OPERATION — DOM-Based Memory Estimation

This tool estimates memory usage by analyzing page complexity through DOM metrics. It counts the number of DOM elements, images, scripts, iframes, stylesheets, and canvas elements on each tab's content, assigning weights to each factor (e.g., iframes are weighted higher as they load separate pages, images have moderate weight, DOM elements have lower weight). The tool also checks for audio/video elements and WebGL contexts, which can consume significant resources. These metrics are combined into a memory score, and tabs are categorized into Low (score ≤ 15), Medium (15-40), High (40-80), and Very High (>80). The score is displayed alongside a color-coded indicator. When closing tabs, the tool attempts to click the close button if available; if not, it removes the element from the DOM. A 300ms delay between closures prevents UI congestion. Results can be exported as CSV with proper field quoting for Excel compatibility, or as structured JSON.

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. The preview updates in real-time as you select tabs or apply filters.

PLEASE NOTE

This tool requires the free BotGentz extension to function. The script estimates memory usage based on page complexity metrics — it does not use the browser's memory API and cannot access actual memory usage data. The estimates are approximate and intended for relative comparison between tabs. 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. Closing tabs removes them from the page's DOM — ensure you review the preview before confirming closure.
