## Description

Ever hit Ctrl+T, paste a link, and realize you already had that tab open three windows ago? Live Tab Deduplication catches it before the page finishes loading.

HOW IT WORKS

As soon as a tab's URL changes to one already open elsewhere, the extension automatically:

→ Focuses the existing tab (even if it's in a different window)
→ Brings that window to the front
→ Closes the newly created duplicate

No flash. No confirmation. Just the right tab, immediately.

⚙️ AUDIT MODE

Not running deduplication yet? Use the "Scan now" button to inspect all open tabs across every window at once.

• Duplicates are grouped by URL
• Each group shows which tabs are "keep" vs "dupe", with their window number and title
• Close individual duplicates with × — or wipe all at once with one button
• Click → on any row to jump directly to that tab

🔧 OPTIONS

• Ignore URL hash — treat <a href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/599eff82249f12e453b9c1b0e2bd92bc3933a6686bbc89b6a091bcaa95fab9ba/http%3A//example.com/page%23section-a" rel="nofollow">example.com/page#section-a</a> and <a href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/9c045a775d4be4efbf89c5ef74b3ccb0fec4cf0cfb621fdff5927e94f2b26e59/http%3A//example.com/page%23section-b" rel="nofollow">example.com/page#section-b</a> as the same URL. Useful for single-page documentation sites; leave off for apps that use hash-based routing.
• Fully togglable — disable Live mode when you intentionally want side-by-side comparisons of the same URL
