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!

This was life saver for me today. It helped me remove duplicates in my bookmarks very easily. Thank you Martin :)
