No Duplicate Tab

Fecha abas repetidas com prévia e encontra favoritos duplicados, mostrando a pasta de cada um para excluir em um painel.

No Duplicate Tab keeps your browser tidy by clearing duplicates in two ways: 🗂️ Duplicate tabs Finds every open tab pointing to the same address and shows a preview before closing: the ones to be closed in red, the one that stays in green. You can uncheck any of them, and hovering shows a thumbnail of the page with its title and URL. The kept tab follows the priority pinned > active > oldest — it never closes all copies of the same site. ⭐ Duplicate bookmarks Lists every repeated bookmark, how many copies exist and which folder each one is in. Delete them one by one or in bulk, choosing to keep the oldest or the newest bookmark. Export a JSON backup before cleaning up. 🧠 Smart URL matching Ignores anchors (#), "www.", trailing slashes and tracking parameters (utm_, fbclid, gclid…) and sorts the remaining parameters, so real duplicates are detected even when links differ slightly. There's an option to ignore all URL parameters. 🔒 Privacy Everything runs locally in your browser. Nothing is sent to external servers. Works with Chrome, Edge, Brave and other Chromium browsers.
