Lost most of my bookmarks... and DAMN I didn't back up first...*(&*%#

#edit dec 4th 2017: I could get a backup and almost have all my (duplicate) bookmarks back.
@Martin: I didn't press an unfortunate button combination. What I did was start the add on, select 'keep first, remove duplicate'and then pressed GO. I have almost 5000 bookmarks in total (dupes included), so the progression bar went by every 20%, until 100% was reached. It then took quite some minutes for Firefox to get up and running, only with just a fraction of the bookmarks that it supposed to have (should have been nearby 2500 left, which it didn't). So there's something with the amount of bookmarks that the add-on is limited to process....

PS: If you want, I can contribute to your project and help translate to dutch

Thanks for the good add-on to check the dupe bookmark!
It's better to add an option to show the complete web address and improve the UI.

Just works. Simple, obvious UI, does what it says without unnecessary garbage.

Amazing -- removed all 700 of my duplicate bookmarks exactly as advertised!

I had 2100 duplicate bookmarks and 100s of empty folders, this add-on cleaned them up in less than a minute.

Just installed this yesterday. I am very happy with the way it works. After X marks butchered my bookmarks, this removed 1000's of duplicates. Thank You for this extension

Simple, visually informative. I'm happy.

查找重复标签的速度很快！但是有的标签没找到两个重复的也会显示到重复的清单中。希望能把相同的url排到一起，方便勾选，谢谢。

Great extension! Works exactly as described. Thanks much!

Fast clean up of a bookmark list full of duplicates

Superb, did exactly what i needed, a cleanup of all dups and empty folders created with an Xmarks sync problem..

Quick and easy to use. It's really great to have option to remove duplicated bookmark in bulk.

exactly what I was looking for

Developed in web-ext.

Thanks!

very very thanks. it's work fine. please update that and add new features. thank you

It works just fine: quick and precise so far. A folder decuplicator/empty remover wold just be the perfect step up in my opinion.
Keep on the good work!
