Just using basic, works perfectly. Had > 5000 Bookmarks to delete. TY!

Great add-on. Very easy , removed all my dup bookmarks in 30 seconds.

It is a very helpful instrument to manage possible duplicates in bookmarks.

good

Saved me so much work! Outstanding!

Saved me few days and removed over 18k of duplicates. Thanks a lot!

I had imported a large file of bookmarks, more than 350 and in multiple folders. Many of those folders were also duplicated.

While it took some time to click check the boxes, I now have clean and tidy list where all URLs are filed appropriately.

Thank you to the authors of this extension.

(Um ... I did look at the Expert option and realised that my HTML was not up to that!

I don't know what people are complaining about.
It worked perfectly the first time I tried it!
All doubles removed!!!
