After re-importing my bookmarks, everything was duplicated. This add-on saved me from the headaches. Works flawless. :)

Works great, very clean design. Topp I was looking for such an Extension since years. Thank you so much.

Thing works like a beast. There's several extensions out there that all say they can do this. I'm not sure if it's Firefox's ability to run well or if the developer just knows what's up. This is by far, hands down, your fastest way to delete duped bookmarks. Great work.

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
