Read the publisher’s full description

Close Duplicate Tabs: The Ultimate Browser Decluttering Tool Close Duplicate Tabs is a sophisticated browser extension designed to intelligently detect, manage, and close duplicate tabs within your browsing workspace. As web sessions grow with multiple tabs opened to nearly identical or slightly varied URLs, users often face unnecessary memory consumption, clutter, and distraction. This extension effortlessly resolves those issues by scanning all open tabs for duplicates and offering powerful one-click solutions to streamline your browsing environment and optimize system resources. Carefully engineered for users who handle numerous tabs—whether researching across related topics or simply seeking a cleaner and faster browsing experience—Close Duplicate Tabs automates the identification and removal of duplicate tabs with high accuracy. The extension leverages an advanced URL normalization process that accounts for subtle differences such as trailing slashes, hash fragments, or small syntactic variations, ensuring true duplicates are accurately detected even when URLs differ slightly. By continuously monitoring tab activity, the extension supports both manual and automatic closure of duplicates, maintaining a neat and efficient tab workspace at all times. Once installed, the extension offers an elegantly designed popup interface that presents a clear summary of all open tabs alongside how many have been recognized as duplicates. From here, users can quickly close duplicates with a single click or adjust settings to better match their browsing habits. The extension also provides customizable options, including a whitelist where you can specify URLs or domains that should never be closed regardless of duplication, thus protecting essential sites from accidental closure. Additionally, an auto-close mode can be enabled to allow duplicates to be removed automatically without requiring manual input, creating a fully hands-off experience. This lightweight tool seamlessly integrates into your daily workflow by using browser-native APIs to minimize performance impact, providing a reliable and responsive tab management assistant. Importantly, Close Duplicate Tabs operates with strong respect for user privacy, collecting no personal data or browsing information, ensuring that your online activity remains private and secure. With Close Duplicate Tabs, users enjoy optimized browser performance, reduced distractions, and a smoother, more productive web experience—all through an intuitive and efficient extension designed to keep your tab landscape tidy and under control. Key Features: - Intelligent duplicate detection through advanced URL normalization, catching subtle variations to find true duplicate tabs. - One-click duplicate tab closure directly from a clean popup interface, saving time and reducing system resource usage. - Configurable whitelist feature allowing users to safeguard important URLs or domains from being closed mistakenly. - Auto-close option to enable fully automated tab duplicate cleanup without manual intervention. - Real-time statistics display showing total open tabs and duplicates for instant overview and management. - User-friendly popup UI with clear controls and informative feedback to easily manage duplicates visually. - Customizable options page enabling fine-tuned control over whitelist entries and auto-close behavior to suit individual preferences. How It Works: 1. Install Close Duplicate Tabs from the extension marketplace. 2. Click the extension icon in the browser toolbar to open the popup interface. 3. View the total count of open tabs alongside the number of detected duplicates. 4. Press “Close Duplicates” to remove all duplicate tabs, retaining one instance of each URL—whitelisted tabs always remain untouched. 5. Access the options page to further customize settings such as whitelist entries and auto-close preferences. 6. Add URLs or domains to the whitelist to prevent automatic or manual closure of essential tabs. 7. Toggle the auto-close feature on or off to enable automated duplicate removal that fits your browsing workflow. Privacy: - No personal data collected.
