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.

Great addon, it checked my 650 bookmarks quite fast and I deleted about 80 bookmarks to sites not reachable anymore. 4 websites were reachable despite marking them as not. But I expected it not to be perfect.

E' inaffidabile!!! trova molte pagine con errori e ti dice di cancellarle, pero di solito il sito esiste e funziona bene, è che la pagina è stata spostata! così cancelli la pagina pensado che non esista più! inoltre non ti da la possibilità di aggiornare le pagine che sono state re-indirizzate!

Does exactly what I needed it to, and even prevents you from being an idiot by telling you to back up your bookmarks.

Perfect!

Just installed on latest Nightly and used to clean up my Bookmarks. Everything worked like a charm removed duplicates and empty (probably left over) folders. I would give 5 starts right now but...when I tried to clean broken urls I really missed the "Folder" info as some links are for customers system and the only way to know it is the folder they're saved into.
