## Description

Bookmark Dupes is a powerful Chrome extension designed to help you manage your bookmarks efficiently by detecting and removing duplicates, empty folders, and clearing bookmark descriptions. With a user-friendly interface, you can easily display duplicates, empty folders, non-duplicates, or all bookmarks and manage them by selecting and removing or moving duplicates to a designated folder. It also features an expert mode for advanced users, allowing custom rules using regular expressions to fine-tune duplicate detection based on URLs or bookmark names.

Expert mode supports complex filtering and URL modification rules to customize duplicates criteria such as ignoring bookmarks from specific folders or considering URLs differing only in protocol as duplicates. Bookmark Dupes supports multiple languages and emphasizes safety with irreversible action warnings and recommendations to back up bookmarks. It does require bookmark access permissions and includes detailed instructions and known bug disclosures for the best user experience. Ideal for users seeking to maintain a clean, organized bookmark library.

## Review summary

Bookmark Dupes is praised for ease of use and strong deduplication, often clearing thousands of duplicates and empty folders. Reviewers cite fast results in many cases and flexible options to keep the most relevant duplicates, plus cross-browser applicability.

Overall, it’s a powerful, user-friendly tool whose usefulness depends on dataset size and speed expectations.
