Tried different tools..... This tool is best one! Recommended.

Thank you great addon, removed about 3000 duplicates in minutes adn so easy to use..

Just tried to use, while trying to move dupes, got this error: Error after moving 2 bookmarks: Error: result.dateAdded is undefined

(worked normally deleting)

Worst ever. It has made a mess into my bookmarks in Firefox, putting all in a "dupe" file ; when I wrote it off, it drove most of my items into "Other bookmarks" in a complete disorder.

Did the job. Easy to use.

Finally, an add-on that is actually capable of delivering its promise with exceptional speed and efficiency.

very useful add-on and makes it easy to delete duplicated bookmarks!

When I reinstalled windows 10 and firefox, I imported bookmarks twice apparently... This app made it easy to find and eliminate the duplicates. I did have a little cleaning to do afterwards (some that were missed), but it very good overall.

This reduced 47,000 bookmarks to 7,000 very quickly. Thanks! The only reason it isn't 5 stars is that I still have to merge some folders by hand. Would be good to have a way to find folders with duplicate names and an offer to merge them. But a great add in all the same!

Had nearly 15,000 bookmarks from years of exporting/importing into different browsers (not cleanly). Helped narrow that list down to 1,900 and remove the empty folders afterwards. Just make sure you don't just delete all duplicates (use a button to pick one from each group).

It works. What else?

Did exactly what it has to do - clear all duplicates in a handy controllable way

Works as charm
