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!

Does exactly what it says on the tin! Extremely useful Add-On. Thank you. :)

What a uniquely POWERFUL addon! It works VERY WELL INDEED! I can't figure out why strings I place into the "Name Matches" or "Url Matches" fields affect the resulting list not at all.

I'm intermediate at regular expressions and I do understand the intended effects of the "filter, modify or does not effect the search" radio buttons, but these seem to have no effect. Why are my attempts at filtering not working?

It would be great if we didn't have to refresh the page and could have a big fat: APPLY CHANGES BUTTON to quickly test various attempts at filtering.

Thank you for the hard work that went into this fantastic and helpful bookmark addon!
