it finds the duplicates but has no button to delete them..

Fool proof duplicate and dead bookmark organizer ... with a huge BUT ... you have to confirm manually every single change to the corrections (redirect, delete, whitelist) ... and since its visual, you can't select the 'ok' by pressing space or arrows, ..... and this can quickly become very very annoying.
Please add an option to disable the confirmation box. thank you.

I know I've got a lot of bookmarks, but it is supposed to help me get rid of the dead ones and duplicates, so that is exactly what I want it to do.

But Firefox always crashes after about 4,000 are checked, 2,700 warnings and 300 errors.

So why, Mr Developer, don't you add the ability to select which folder of bookmarks to check? Or specify a number of bookmarks to check and then stop, so we can deal with some of the checked bookmarks before it crashes Firefox?

...just an idea.

Бро, все конечно круто... Расширение не позволяет автоматизировать процесс удаления дубликатов, все равно приходится делать это вручную. Удобнее даже через стандартное окно "все закладки".
А еще эта анимация с окном подтверждения... Не хватает только 3d эффектов на UNITY )))

funciona correctamente

Dopo aver cancellato molti bm segnalati come errati, mi sono accorto che invece erano ancora attivi. e non ci sono altre funzionalità...

I was able to reduce my bookmarks from 1,581 to 534 by just getting rid of broken, obsolete and duplicates. That is a huge help for now going on to organize them into proper folders.

Looks like extension doesn't work

Couldn't find any actions to perform on all my duplicate bookmarks. Hence the whole thing felt completely pointless.

I checked the top of the list, the bottom of the list, the page header, the page footer...

This tool is fantastic. I have almost 2k bookmarks, and trying to de-duplicate and find old, dead bookmarks by hand is a huge pain. This add-on was able to identify several hundred bookmarks I could prune and made it easy to fix broken bookmarks I wanted to keep and remove dead bookmarks. Thanks Sören!

Simple et efficace. À utiliser régulièrement pour garder ses marque-pages propres. Merci.

Bis jetzt funktioniert alles bestens, Firefox läuft rund, sehr praktisches AddOn, endlich mal Ordnung im Lesezeichen-Dschungel. Manche schreiben vom Ordner, der nicht gefunden wird?! Ähm, Mozilla-Ordner suchen und gut ist.
