very useful addon for me and works fine here with Fx 59beta, it founds all duplicate and invalid Bookmarks, great work!

Ja das stimmt.
Also das Entfernen von Duplikaten sollte automatisch gehen, d.h. man sollte eine Regel angeben können, nach der nur noch eines der Duplikate beibehalten wird (z.B. nach Datum, nach Abfolge gefunden, Verzeichnistiefe oder so)
Ich habe ca. 9000 Lesezeichen, von denen einige Duplikate sind (~200). Diese einzeln zu suchen und dann auch alle mittels eigenem Klick zu entfernen ist sehr mühsam.

Great idea, but very slow for me. FF Quantum 58.0.2 (64-bit). 30MB/sec internet connection.
Scan started. Number of bookmarks: 9776
Somewhere around 9200 Checked it slowed down considerable.
After 9600 it slowed down so much I thought it stopped.

It is still checking, so I guess it is working.
It's Checked: 9638 Warnings: 4355 Errors: 2698
It has taken me over 20 minutes to get this far and at the current very slow rate it will take another 4 hours.

I assume it will have a method for fixinig errors and removing duplicates. I don't se that menu choice while it is scanning

Never completed scanning all bookmarks and I can't see how to fix errors and delete duplicates.

Great idea, but so many false positives that it makes it worthless. Can only give it one star until bugs fixed. This should have been released as "alpha" version.

von ca. 2300 bookmarks werden 2297 in wenigen minuten gescant, die vorletzten 2 brauchen 10 minuten, die letzte ist auch nach 30 min. nicht gescant - ein zwischenergebnis über 2299 gescante bookmarks wird nicht dargestellt. absolut unbrauchbar.

Perfect for cleaning up my bookmarks

Le tri des doublons n'arrive pas à terme

It does not work! Whith each runcycle the addon detects new, not working URLs (while some of these work!) and after deleting these new ones occur again.
And it takes ages to scan all links (seems there is no good delay after which not working URLs get aborted)
No control what the addon does. While it works in the background one cannot see if it crashed already.
No chance to interrupt or see intermediate results. No batch processing of links. I would not recommend it.

After having deleted not working URLs and starting the Addon again, the addon detects new entries which it did not durung the first run? So it does not work reliable... be aware.

Very good addon and very good design !

The only lacking features:
- an option to be able to disable the http to https redirect warnings.
Because I use an automatic http to https redirector (extension : Smart HTTPS), so all HTTP urls are in Warning...
- a new functionality to be able to list the empty folders

It get stuck at last bookmark and then i have to restart Firefox...

What happens after it identifies all my bookmarks? I want eliminate duplicates, but I don't see any action tab to perform this function??

Works very well on my 600+ bookmarks. Will rate 5 stars with whitelisting and ignoring redirects for keyword search URLs. Would also be nice if it differentiated 404s from connection resets.

Doesn't work

Brilliant addon. Makes it so easy to correct redirects, remove duplicates and to edit broken links. Have patience it does take a while to finish checking the last few bookmarks.

«The AddOn found many broken links very fast. But the process stopped 1 link before the end and stays there endless. Process doesn't finish.» Pretty much that. Besides, once I refreshed the page to try it again it was impossible to even start the process.

Great

Freezes

Working with FF 57.0.2. (64 Bit)

Searching for broken or unavailable links:

The AddOn found many broken links very fast. But the process stopped 1 link before the end and stays there endless. Process doesn't finish.

Searching for duplicate links:

The AddOn doesn't show any duplicate links, but starts to delete links without my confirmation. A look into the FF bookmark backups showed me, that there where really nearly 100 bookmarks deleted.
So I closed the tab of the AddOn hoping this will stop the process. In this moment FF crashed. After starting FF again, ALL my bookmarks were lost.


I hope you understand my rating. I deleted the AddOn for now.
It's a pitty because FF seems not to able to created an integrated bookmark organizer. So i still hope you get this AddOn work bug free.
My best wishes for that project.
