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

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

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.

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

Very useful and does what it is supposed to. You have many options to choose from, which is great and my bookmark folder never looked better! Every time I'd sync between devices, I'd have even more duplicates and there were thousands of them, very annoying!
Thank you very much!
