BookmarkDuplicateFinder

Over time, bookmarks accumulate — imports, re-saves, and browser syncs often leave you with the same URL stored in multiple folders without you noticing. Bookmark Duplicate Finder scans your entire bookmark library and identifies every URL that appears more than once, showing you exactly where each copy is stored. How it works: Click the extension icon and hit Scan Bookmarks A results page opens showing all duplicate URLs grouped together For each duplicate, select which location you want to keep — the rest are marked for deletion Click Delete to remove the unwanted copies Key features: Displays the full folder path for each duplicate so you always know where a bookmark lives When a URL has 3 or more copies, you can keep multiple locations at once Bulk delete across all duplicates in a single action Clean, minimal interface Privacy: Your bookmarks never leave your browser. The extension reads and modifies bookmarks locally — no data is collected, stored, or transmitted anywhere.
