better than other bookmark extensions because allows automatic bookmark removal, and very fast and compact layout, just bad that some people may accidentally remove all bookmarks after finding dupes if they mark and delete all bookmarks, they have to know mark only but first or last should be used, but hopefully they backup bookmarks

Wonderful.
No dangerous permissions.
I use it by clicking the star.
Then "dupes".
Then "mark all but first in each group".
Then, optionally, if I don't want it to touch some folders, f.e. SessionSync, I click "Select a folder to get ...".
Then "Unmark all from selected folder".
Optionally, repeat the last two steps.
Finally, I click "Remove marked bookmarks."

Thanks a lot for this :)

Outstanding, worked like a charm, quickly.

fast and customizable bookmarks deduplicating

Does exactly what I need it to:

"Bookmark Dupes" can remove all duplicates found within bookmarks in just a couple of clicks. Super easy!

easy to use and clean UI. grate job and thank you for removing my 120042 duplicates.

Well, I had one job to do and Martin your tool did so simply! Thank you so much. Hours of work saved! I love the fact you haven't just thought of DUPES but also NON-Dupes! Thanks again

I had thousand duplicate bookmarks (was testing some sync app) and removed them with just 2 or 3 clics. Perfect sumum of efficiency !

Dups found. I choose what to keep, dupes gone! Lovely

Simplest, without hassle dupe cleaner. Loved it.

Simple but a very powerful tool. It's also very intuitive despite the old school, no-nonsense GUI. Worked like a charm and saved me so much time. Thank you very much!

I have been trying to delete over 3000 duplicate entries. I have spent over an hour an still had over 3000 left. Installed this app, clicked on three filters and gone! I now have a few over 300 entries in various folders. And all in less than 5 minutes including download and setup. One of the great filters allowed me to select the first item in each group. The duplicate data was presented in groups with similar/same associations. By selecting the fist in each group an delete all the other entries in that group some had 40+ entries of the same site. I did make a backup of my favorites before I hit the delete key.
