Kill Clone Tabs

Find and close duplicate tabs. Sort, group, and manage tabs. Highlight text on pages. Copy tab URLs. Boost your productivity! Kill Clone Tabs helps organize Chrome without a remote application server or analytics. • Find and close duplicates across normal windows, with independent matching options for URL parameters, fragments, slashes, protocol and www. • Spot duplicates immediately with highlighted popup buttons, a live count and a toolbar badge. Preview which copy stays and which tabs close before manual cleanup. Last-cleanup feedback is shown separately from the current remaining duplicate count; tabs that navigate are skipped safely. • Turn automatic duplicate cleanup on or off from the popup. It starts off by default; turning it on also cleans existing duplicates using your chosen retention rule. • Keep the active copy, or the first/last copy by window and tab position. Save protected domains to exclude them and their subdomains from cleanup. • Select duplicates in the current window, sort by URL or hostname, create native groups, pin/unpin and mute/unmute tabs. • Unfinished close requests return a visible incomplete result after a short wait. Remaining tabs stay open; resolve any unsaved-page prompt or close that tab yourself before another recoverable action. • Undo cleanup and tab organization even after closing the popup. Recovery can reopen URLs and restore positions, windows and group metadata, but cannot recover unsaved page state. Recovery lasts until browser restart/extension reload. After Undo, both copies stay open through automatic scans and focus changes. Reopened copies are excluded until their URL changes; explicit manual cleanup can still remove them. • Copy tabs, export HTTP(S) URLs as Markdown, and import multiple URLs from files or pasted text. • Highlight selected text with case, Unicode whole-word, color and length controls. Match across inline elements within a block; display up to 10,000 matches, including after page content is replaced. • Search tabs using keyboard-accessible results and receive status feedback. • Selectively close tabs and remove Chrome history for domains in your local hide list. Protected domains are excluded. Partial failures are reported. Cookies, downloads and server logs are not cleared. Ordinary settings may use Chrome Sync. Sensitive domain lists and the PIN verifier stay locally. The PIN hides the list in the settings screen; it is not encryption. No analytics, tracking, or remote application backend. Popup and Settings share light/dark themes, readable labels and consistent controls. Settings feedback stays visible while you edit. Requires Chrome 105 or later.
