So easy to use, so quick to clear all dupes!

helpful but could use a better UI. For example, ability to hide results or ignore certain bookmarks or entire domains (ie., google.com/*)

Waste of time. Wish I had taken the previous 1 and 2 star ratings to heart.

I use this extension on both Chrome and Firefox.
It does 4 things, and does them well, so I've preferred it over other similar extensions.

However, removing duplicates seems to trigger a memory-leak-like bug in Firefox, which quickly increments memory usage until the system grinds to a halt; this doesn't happen in Chrome.

Problem aside, I definitely recommend the extension over others.

Conforme a la philosophie Unix : Ne fait qu'une chose mais le fait bien. Chaque action est bien séparée. L'interface est simple et claire. Pour moi c'est un modèle que d'autres extensions devraient suivre...

簡單直覺，我覺得比令一個高分的擴充套件好用。

Perfect! The perfect all in one extension I didn't know I needed.

The "broken urls" and "remove duplicated folders" features are great, works really well.
But the other functions doesn't work at all. The "find duplicated" feature finds all the bookmarks that it should do, but the deletion doesn't work as expected.
