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

does delete dupes, but I can see no way to organize the remaining bookmarks. So you wind up with tons of duplicate folders and no way to delete dupe folders and organize remaining bookmarks.

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!!!
