Tab Dedup

Detects duplicate tabs and offers to switch to existing ones. Keyboard navigation and custom domain rules.

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.
