Tab Dedup

About

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.
