Tab Closer

Tab Closer closes duplicate tabs that match by URL and title — and keeps the important ones open. WHAT IT DOES • Matches duplicates by URL and title • Waits for pages to load before deciding • Keeps one original tab • Protects active, pinned, and audible tabs • Review what will close, then Undo if you change your mind • One-click toolbar mode when you want speed • Site exceptions for domains you never want touched WHO IT’S FOR • Anyone who reopens the same doc or product page by accident • Tab strips that quietly grow clones of the same URL • People who tried aggressive auto-closers and lost a tab they needed HOW TO USE 1.
