Review-Update: Einige Bookmarks werden kommentarlos als fehlerhaft angezeigt, obwohl sie sich ganz normal öffnen lassen. Es sollte der Grund angezeigt werden, warum es einen Fehler gibt. Im Ergebnis werden bei mir 12/437 Lesezeichen als false positives angezeigt. Insbesondere mit Google-Seiten scheint die Erweiterung Probleme zu haben.
Im Vergleich dazu zeigt die Erweiterung "Bookmarks clean up" immer einen Grund an. Hier gab es aber nur ein false positive wegen eines Timeout, der nach erneutem Test auch nur temporär war, sprich keine systematische Anzeige von Lesezeichen als fehlerhaft.

Einträge ohne Namen werden aufgrund des fehlenden Grundes genauso angezeigt wie in der Suche nach leeren Namen. Daher entsteht der Eindruck, der Grund sei der fehlende Name. Das ist ein Problem des Interfaces.

Der einzige Vorteil dieser Extension ist, dass man Weiterleitungen auf einen Klick übernehmen kann.

It's really strange to have a duplicate finder that has a popup with no hotkey support. I have over 3,000 duplicates and there's no way I'm clicking 6,000 times to fix that using this addon. There needs to be a selection assistant, preferably something like Duplicate Cleaner has (this is not an addon, its a standalone software for files).

The results for checking broken bookmarks aren't visible until the whole search is done. I have over 15,000 bookmarks saved, I don't want to wait an hour and a half every time I want to clean out some broken bookmarks. It would be more usable if it could divide bookmarks up into batches so you can go for, say, checking just one thousand bookmarks at a time, preferably the latest 1,000 you added.

I hate to rate this addon two stars because this one technically works great, but the usability is so low that I really can't picture myself getting any work done with it.

Hi, am perfectly willing to change my rating - but as of right now = I get zero results. I had it run one week ago for a full day. It simply showed "0" on everything.
I have 124792 bookmarks [well, am online since 1993 :)]
So, it is virtually impossible that there is none broken, or double etc. I know for a fact that I have at least over 20 thousand doubles, because of a inadvertent new import after Xmars closed.
That was my reason for installing your extension, hoping to clean first before I use bookmarks also with my FVD account I have for speed dials.

Yes, of course I can do a manual check and clean with the library, but this would be silly if a extension like yours exist.
I have:
Firefox quantum 60.0.2
Your extension version: 2.0.1
I read over every comment here without being able to determine anything to solve my problem.
Hoping you will respond to the low star mark - and maybe there is an explanation for zero results.

I also tried it on my laptop, that is not synced to anything. The only identical setup is the old Xmarks bookmark folder structure.
I always kept the Xmarks clean on all my cpu's [had used them from their initiation date].
I should be able to get at least some number of duplicates from your extension.
Tests I did following last weeks zero result after an entire day run: Tried also with a new mozilla profile,
but still get no results.
I see that others here have no problem, so I need to find out what and why I get no results.
Kind regards,
Michele
Ps: ich spreche auch Deutsch, sollte das fuer sie einfacher sein.

Overall it looks good and useful, however:

1) It doesn't explain why some bookmarks give an error
2) It returns as "errors" perfectly working bookmarks.
E.g. https://addons.mozilla.org/en-US/firefox/addon/ublock-origin/?src=search - It works fine but it's flagged as error
3) It should allow correcting multiple warnings/errors
4) Bookmarks paths are incomplete. This is very bad when trying to eliminate duplicates.

EDIT: that's it. After a couple of interactions it stopped working (I click check and nothing happens. Tried to close and reopen the tab, but it didn't solve. I'm going to uninstall it.

I can't figure how to use it. I had it search for "ERRORS". It found several, identified by a red dot in the HTML file it created, but my version does not have the delete all broken bookmarks thing to click on. Deleting them manually
would take a long time, but that does not work. I delete them in the HTML file, but they are still in my FireFox bookmarks.

It found about 5000 "Warnings" but I don't know what it is trying to warn me about.

I see in other review answers that I should be using version 2.0. How can I tell which version it is?

OK, now I can see it is version 2.0.1 by looking at the addons manager in firefox.
Is there a better way for me to reply other than editing my original comment?

I still cannot see a delete anything link. I took a screen capture. How can I sent it to you?

The Icon at the upper right says Hey. looks like there is a lot of cleanup to do, but does not show how to do that.

I've installed it and I have a screen with a little box with 3 options of analysing bookmarks.

There are three balls rippling back and fore from small to large which I presume is telling me summat's happening, but - nothing's happening.

Half an hour now and Zero Bookmarks in the box on the screen.

Am I missing something ?

There IS also a box in which the words "Check bookmarks" appears. It is greyed out and cannot be selected.

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.
