Close Duplicate Tabs & Group by Type - Dedup NewFun

DedupNewFun cleans up browser tab clutter, duplicates, empty tabs, and scattered windows full of the same handful of sites without sending anything anywhere. REMOVE DUPLICATE TABS One click to close duplicates by exact URL, or by domain (keep one tab per site). The tab kept is chosen by priority: pinned, then active, then oldest. A tab is never closed if it looks like doing so would lose unsaved work — an open form, an ongoing edit, or a page that asks to confirm before leaving. CLOSE EMPTY TABS Clears out every blank "New Tab" page in one click. Tabs you've deliberately pinned are left alone. GROUP BY SERVICE OR FILE TYPE Creates native Chrome tab groups for different services plus a dedicated group for any open PDF, Word document, spreadsheet, image, or other file, regardless of which site is serving it. Add your own custom rules (a simple text match, or a regular expression) from the options page. ADVANCED PREVIEW A full-page list of every open tab — favicon, title, domain — sortable by domain/type and searchable. Click a tab for an on-demand screenshot (nothing is captured until you ask for it), mark tabs for closing as you go, then apply them all in one click. DUPLICATE A TAB Double-click a row in the advanced preview to duplicate that tab (off by default — turn it on in Options), or press a keyboard shortcut (default Alt+Shift+D) to duplicate whichever tab is currently active, anywhere in the browser. PRIVACY No data collection, no analytics, no telemetry, no network requests other than the pages already open in your own tabs. Every setting — scope, sort order, custom rules — stays on your device via Chrome's own sync storage.
