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!

I have been trying to delete over 3000 duplicate entries. I have spent over an hour an still had over 3000 left. Installed this app, clicked on three filters and gone! I now have a few over 300 entries in various folders. And all in less than 5 minutes including download and setup. One of the great filters allowed me to select the first item in each group. The duplicate data was presented in groups with similar/same associations. By selecting the fist in each group an delete all the other entries in that group some had 40+ entries of the same site. I did make a backup of my favorites before I hit the delete key.

Easy to use for removing duplicate bookmarks, empty folders. Easy selection of items for mass deletion.

This Addon is great. Just the UI isn't that great for first time user, I hope this ability is built in in Firefox so we don't need to install 3rd party plugin, but this Plugin is great!

Thank you for creating such plugin :)

Smart, quick, batch identifying and removal, that's all I need. Thank you very much for creating this add-on!
