Quand on a quelques doublons, l'UI est suffisante. Mais quand on a quelques centaines de doublons, l'interface de cet add-on n'est pas efficace ou suffisante.
La suppression est extrêmement lente.
En tant que développeur, je ne peux pas soutenir une application pareille.

#1 neither gives you an option to save AT LEAST ONE of the duplicates it finds, NOR warning that it will delete them all, no toggle, no nothing, it just does it,

#2 slow to delete once it has given you the delete-confirmation dialogue,

#3 also struggles when browser has duplicates from past carry-over from previous browsers and one has not been constantly reducing them each time - i had over 1500 bookmarks, and by the end of it, it had deleted almost all of them, ONLY LEAVING the ones not conflicting, which were a very small list of brand new ones i'd done after reinstalling windows but BEFORE importing my previous bookmarks,.. and on top of that,

#4 it could only handle 50 or so at a time, which i had to select by using TinyTask, because there was no rapid way of selecting them, NOR select-all, nor any other filtration or sorting functions, to select groups, etc. Literally single-click by single-click,.. no thank you,.. thank you TinyTask...

#5 but even then, at the end of it all, i had to RE-import all 1500+ ... because it had neither warned nor given any options for leaving at LEAST ONE, of the ones it found. About the only reliable function it had, was finding ALL that matched. Worse than expected.

The UI is actually intuitive to use despite another review that nearly discouraged me to try this add-on. You simply select the extension from the toolbar, click Find, then checkmark which duplicates you want to remove, and finally click the Delete Selected button at the top of the list. Easy-peasy!

It works! And, it's very easy to use.

It finds them...that's about it. UI is insane. Results pop up in a small panel that requires crazy horizontal and vertical scrolling with no way to do anything about the duplicates it finds. Opening the options shows a completely black panel with toggle switch for something. Results conversely are blinding white. I'm guessing it doesn't conform to the users UI theme correctly.

Actually works even in nested folders, unlike the "popular" bookmark extension. The GUI could be improved though to something not so large and adjustable. Great job otherwise! 👍

PS Do you have one for Chrome?

Did not find any duplicates, although there are. Maybe because duplicates are in nested folders.
