Tabs Doctor Ultimate

Diagnose and close duplicate tabs across all windows — sleeping, blank, and chrome:// pages too — with rules you can read.

The only tab-deduplicator that actually works. Most dedupe extensions are broken, half-finished, or abandoned. Tabs Doctor Ultimate finds duplicates across ALL your windows — including sleeping tabs, blank/new-tab pages, and chrome:// pages — and closes them on a click, on a timer, or the moment they appear. ▸ THREE WAYS TO CLEAN UP • Click the toolbar icon — open the popup, or set it to close every duplicate instantly. • Auto-close as soon as duplicates appear. • Auto-sweep on a timer — 30 sec to 1 hour. ▸ MATCHING — YOU DECIDE WHAT'S A DUPLICATE • Ignore case, www., subdomain, anchor, query string, or path. • Optionally require the page title to match. • Group blank / new-tab pages (multiple about:blank → flagged). • Works across schemes: http(s), chrome://, chrome-extension://, file://. ▸ KEEP THE RIGHT TAB Pick newer / older / leftmost / rightmost / focused. Always prefer https. Always prefer pinned tabs. ▸ SCOPE & WHITELIST All windows or current only. Skip URLs containing your whitelist patterns (Gmail, Docs, dashboards). ▸ PRIVACY No data collected, transmitted, or shared. No accounts, no tracking, no remote servers. Settings are stored locally via Chrome sync.
