Tab Dedup

Tab Dedup helps you manage your tabs by automatically detecting when you're about to open a duplicate. Instead of creating another tab for the same website, it shows you a clean interface where you can: • Switch to an existing tab with one keypress • See all matching tabs across all windows • Open a new tab anyway if you really need it KEY FEATURES ⌨️ Full Keyboard Support Navigate with arrow keys, confirm with Enter, cancel with Esc. Fast and efficient. 🎯 Smart Domain Matching Configure domain aliases to handle redirects (e.g., gmail.com → mail.google.com) 🚫 Disallow List Exclude domains where you want multiple tabs (like search engines or localhost) 🔒 Privacy First No tracking, no telemetry, no external servers. All processing happens locally. ☁️ Chrome Sync Settings sync across all your Chrome devices automatically 🐛 Debug Mode Optional detailed logging for troubleshooting and bug reports HOW IT WORKS 1. You open a new tab and start typing a URL 2. Tab Dedup checks if any existing tabs match that domain 3. If matches are found, you see a chooser interface 4. Select an existing tab to switch to it, or choose "Open new tab" 5. That's it! No manual searching through dozens of tabs PERFECT FOR • Developers who work with multiple documentation sites • Researchers who open many reference pages • Anyone with 20+ tabs open at any given time • Power users who want better tab management CONFIGURATION The extension works great out of the box, but you can customize it: • Domain Aliases: Map redirecting domains to their canonical form • Disallow List: Exclude specific domains from duplicate detection • Debug Mode: Enable detailed console logging for troubleshooting All settings sync via Chrome's built-in sync, so you only configure once. PRIVACY & SECURITY Tab Dedup respects your privacy: ✓ No data collection ✓ No external servers ✓ No tracking or analytics ✓ Open source on GitHub ✓ Only stores your configuration locally TECHNICAL DETAILS • Built with Manifest V3 (Chrome's modern extension architecture) • Lightweight and fast • Full keyboard navigation • Works across all Chrome windows • Settings sync via Chrome Sync SUPPORT Found a bug?
