Rated 1 out of 5 stars

Though I was able to install it on Firefox 26, it's realy not worth the trouble as:
- listing the dupes is the only working feature of this addon on newer Firefox
- other, up-to-date addons* does the same job (and more), without having to force the installation of an older, Firefox 1-3 addon.

* e.g. Bookmarks Checker by FVD Media, or Bookmark Duplicate Cleaner by Anders Lindmarks which shows you the folders where the dupes are located :-)

outstanding Rated 5 out of 5 stars

does exactly what it says- deduplicates bookmarks.

a little quirky to invoke, you gotta go to Tools, Add-ons, Preferences, Start. Also with ~2000 bookmarks, you gotta tell it "yeah, continue running the script" once or twice.

But it works great, even with firefox 24, though I had to use Install Anyway on that one.

Was nice, now broken Rated 2 out of 5 stars

- Duplicates listed, but you cannot select a copy of it and thereby not delete duplicates

- Does no longer warn when adding a url to the bookmarks a second time

so all the addon can do currently is list duplicates!

Please Update for "complete" functionality for Firefox 22 !!

Usability improvement ideas Rated 3 out of 5 stars

Plugin is useful and works.
Due to a broken sync plugin, i have to cleanup hundreds of duplicate bookmarks - this consumes currently a lot of time.

Ideas for enhancements:
- If multiple bookmarks are marked to be removed, it would be useful to just confirm that all the marked bookmarks should removed.
(currently you have to confirm every single remove)
- provide an option to open the URL of the duplicate bookmark
(in the plugin window which shows all duplicate bookmarks)
- detect duplicate bookmarks in the same folder, and remove them automatically
(just ask, and remove them after confirmation)

Updated Version Available Rated 5 out of 5 stars

If you're looking for a version that works with Firefox 12 or higher (including 13), head to the developer's site. (the link to his site is in the description above) Once there, head to the Installation page and read the notes before installing the add-on.

If you intend on having the extension delete all duplicates, I would suggest that you first make a backup of your bookmarks (I use FEBE) before making the attempt.

Hello is it compatible with 10.0.2 in spite of the warning ?

It Used to be Much Needed Rated 3 out of 5 stars

Used to be very needed but it hasn't worked correctly for a few versions back of Firefox.
I would use it again if it were properly updated.
Do we need this anymore in the new versions of Fx??

Rated 1 out of 5 stars

Once it gives me the message "Confirm", it gives me only two choices, either to "Add it" or "Cancel". Unless "Add" is clicked, it continues to repeat it self. It will not "Cancel" and the dialog box will not close. What it needs is three choices - "Yes", "No" and "Cancel" with it closing.

Hey man, update that for FF8. I love it and I need it.

BDD still only one and best Rated 5 out of 5 stars

Die Anwendung mag nicht prefect sein, sie lässt sich sehr gut anwenden, deckt die notwendigen Evtl. bei doppelten ab dabei gilt der Grundsatz ... wer lesen kann besonders englisch - ist klar im vorteil und bei fehlern kann ich das nicht beurteilen, hatte keine !
Die Aktualität zeitlich zu den FF Updates : auf der Homepage gab;s immer die gängige Version, obwohl Mozilla's Site noch nichts hergibt!! So wie jetzt wieder!!
An dieser Stelle einen Dank an den Prog, wie alles gratis, online Verfügbare - ohne sie hätten wir ... Nichts!!

Support for Firefox 5 here:

I installed that version in Firefox 6 and it installed without complaining. I have yet to test how it runs, though.

Rated 5 out of 5 stars

Have been using it on previous FF versions. Please update for v.6 too!

Unable to install in 5.0 Rated 3 out of 5 stars

@ zapyon: I tried to install the add-on, but Firefox itself doesn't complete the installation. 'Unable to install as it is not compatible with 5.0'. I give three stars as the idea is good, but I was unable to try it.
