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!

Den gør arbejdet men ikke specielt hurtigt eller kønt

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.

IMPARFAIT... lopu certains bookmarks en double

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!
