Seems to work, but I miss the tags: either display the tags set on each bookmark, or offer to merge the tags from deleted bookmarks into the remaining ones.

Very Good :)

Rated 5 out of 5 stars

Very useful and precise thanks to folder display. The only downside is very slow going - it takes three clicks per duplicate bookmark to clean it, so I hope you would consider putting all bookmarks in a single list with each group separated by a separator and a cross to delete the respective entry without having to select it.

Bookmark duplicate cleaner removed several duplicated bookmarks for me.
One note that the extension does not yet prevent you from adding a duplicated bookmark. Bookmark duplicate cleaner is useful good extension if you use and create lots of bookmarks.

Needs an Option to ignore Bookmarks Toolbar entries. Rated 3 out of 5 stars

I can't use this unless it will ignore the duplicates that exist in the Bookmarks Toolbar. I want some bookmarks to exist in my highly organized bookmarks Menu as well as in my Bookmarks Toolbar. Please consider this. It's unusable for me without this.

Works as stated.

Most of the low marks are people having problems with it due to their own fault or they are those who expect it to do more than advertised.

Deserves 5 out of 5. Thank you for the great addon and happy new year.

FF 33.1 Rated 1 out of 5 stars

dont work in FF 33.1 i dont see the icono

Works for me in 33.1, and 34.0.5. Don't know what icon you are talking about, as there is no icon.
You either:
* press the Bookmarks-menu and click on "Bookmark Duplicate Cleaner"
* press the Tools-menu and click on "Bookmark Duplicate Cleaner"
* press the firefox bookmark-icon to the right of the star-icon by the address bar and click on "Bookmark Duplicate Cleaner"

Performs Exactly as Advertised Rated 5 out of 5 stars

(Firefox v. 33.1 or so)

Great job, Anders. BDC has worked flawlessly every time.

I recently installed and ran BDC on my old Win XP notebook and new Win 7 desktop. BDC produced the duplicate list instantly on both and reported at least a hundred duplicates on each. Some duplicates I wanted to keep, while most I didn't realize I had and I didn't want. I stepped through them and deleted those I didn't want.

I then exported my XP FF bookmarks to .html, moved the file to my Win 7 system, and imported them into FF. They ended up at the bottom of the Win 7 FF bookmarks, of course, which made them obviously the imported ones. I then ran BDC and went through and deleted each imported XP bookmark that was shown as a duplicate. I had 100 or more that weren't duplicates, which I then moved into the appropriate Win 7 FF bookmark folders.

Yes, this all took 2-3 hours, but only since it was the first time. Since then I run BDC on each about once/week, and delete the 1-2 duplicates I've managed to add. Simple, easy.

To the reviewers who have complained...

- Yes, going through the duplicates the first time can be tedious, but a program can't do your thinking and selecting for you, unless maybe you just want to delete all but one instance.

- Most importantly, the author wrote this on his time and his dime, gave it to you free, and it works. Show some appreciation. If you would like more or different functionality, make a respectful suggestion and request.

There are a few things I'd like to request.

- Let me export the bookmark folders, titles and bookmarks to an ASCII text file (for example, I often want to send a list of links to someone). For example:

... Shopping (Folder name)
...... Auction Sites (Subfolder name)
......... eBay (Site title)
............ eBay.com (Site link)
... Shopping
...... Auction Sites
......... Other sites
............ BidOnSomething.net

- Identify empty folders/subfolders and let me delete them if I want.

- List bookmarks that point to the same web site; maybe I only need one of the links.

- Add dead link checking. However, if a web page is gone, tell me if the web site itself is still there, and change the link accordingly if I say to do so. If "aaa.com/bbb/ccc/ddd" is gone, but "aaa.com/bbb" remains, let me say to change the link to "aaa.com" or "aaa.com/bbb", for example.

- Allow me to merge the bookmarks in one folder into another folder.

Thank you!

it good

Strange Rated 2 out of 5 stars

Addon's interfacce doesn't seems like an image above, so it can only analyze bookmarks and remove _some_ duplicates (i can't choose which one must be deleted)

Needs to be quicker Rated 3 out of 5 stars

I have over a thousand dupes and it would be great if I could use keyboard shortcuts like ctrl-d on each one I click on or be able to highlight all bookmarks and delete them all at once. Or use checkboxes to select all and delete all. I know your working on this and I look forward to the update. Thanks for helping.

Хорошее дополнение. Без лишних усилий удалил дубликаты ссылок. Буду использовать в дальнейшем.

I will delete manually myself, this addons will be done automatically.

Rated 3 out of 5 stars

Not a bad extension. Would be better if it supported keyboard shortcuts, i.e. tab/enter support (can be a lot of clicking).

Rated 5 out of 5 stars

Just what I was looking for! As I do a lot of research and preparation work across several linked subjects, I do sometimes want duplicate bookmarks. But every so often, a spring-clean is required, and this add-on enables me to see exactly where a bookmark is duplicated (even triplicated etc!) and therefore whether I want to keep multiples of it or not. What I didn't want was a blunt tool that deleted all duplicates in one fell swoop. Thank you!

Works as promised.

Right idea Rated 1 out of 5 stars

Without auto deletion or multiple selection it makes it a little annoying to use.

Manual Delete - Rated 2 out of 5 stars

VERY quick in finding duplicates, but I have roughly 2,K+ duplicates, I will not be deleting manually. When your other options, auto-delete or multiple delete options, become available, then I will re-review.

Ridiculous manual labour Rated 1 out of 5 stars

Because of FF stupid sync I now have 122 duplicates... do you really expect me to delete them one by one? Godsake.

No I don't expect you to do that, and neither have I made any claims that the extension will do it for you. That will come in a later version sometime in the future, but until then this extension won't help you.

Merry Christmas

Useless there is no option on my installed version to find duplicates and it makes no effort to find them by itself. I have installed it on 2 computers and it does nothing on either., pressing the firefox button at top left gives me the option to restore minimize or close. Nothing else.

I don't understand what you mean by "no option". Have you pressed the Bookmarks menu and then clicked "Bookmarks Duplicate Cleaner"? Alternatively you can press the Firefox-button on the top-left of the browser and then "Bookmarks Duplicate Cleaner". It scans for duplicates when it launches the window.
