Very helpful

worked well. thanks dev
Firefox should have this as feature.

Does the exact thing it says it does, provides easy macros to select all but one of each duplicated bookmark then erases them all. It does all this on its own page preventing the "popup goes away with all your work" problem. Little more could I ask for from an extension of this type.

Super, ce module, il fait exactement ce que j'attendais. Plusieurs choix sont possibles pour marquer automatiquement les doublons (Dups) ou alors à la main.

Unpretentious and practical. When it finds duplicates it asks which to select (newest or oldest entry).

Amazing extension!
Due to constant import/export from/to other browsers I had a total of 15k bookmarks.
This extension removed the dupes with a single click to 3k bookmarks within minutes.
Highly recommended.

Seems like there is a bug regarding capital vs non-capitalized folder names. After running the "Moved marked bookmarks to 'Dupes'" command, any of my folders with a non-capitalized name were left without any bookmarks in them. The non-capitalized folders were empty.



EDIT: User error, the plugin is working as intended!

Super! (and amazing that Firefox doesn't have this essential functionality buit-in!)

The best in its kind.
