It is currently useless because it is not supported by Firefox Quantum. This is not a criticism of the add-on but of Firefox for not maintaining backward compatibility. I would put it as a very high priority that Firefox Quantum restore backwards compatability. This is the third add-on I cannot use because I have automatically been upgraded to Firefox Quantum without a major warning that it breaks add-ons.

As a request to the author can you join the, I suspect hundreds of, other add-on writers who are now playing catch up because because firefox have broken one of the fundamental rules of software development Keep it Simple: in this case for people to maintain their add-ons.

Use this Add-on cautiously

Today, 11/5/20179, I tried Deduplicator for the first time using FF56. Unfortunately it removed Bookmarks that I did not consider duplicates. Because of the way I save and organize Bookmarks there may be no solution since I provide my own Bookmarks' name in properties. Some are located elsewhere. I had THOUSANDS of bookmarks, so I should have deleted the Bookmark duplicates individually. At this point I don't know if deleting individually is an option. So this is more an advisory for those who are trying this like me for the first time.

I use FEBE (by Chuck Baker), which I recommend so this issue can be overcome to return to a previous Bookmarks backup.

I'll re-rate this once I get more experience using it, If I'm able to get it to work on the thousands of Bookmarks I do consider to be duplicates they will have to be handled manually. This will require that the Parent Folder be identified.

I'll be looking for a way to isolate those I do not want deleted within my system of organization and just let the Deduplicator work without doing it manually. That actually is a requirement in my case due to the large number of duplicates.

Hands Down The Best Deduplicator for Firefox Rated 5 out of 5 stars

Its simple, its clean, it has a job and it does it well. It would be nice if there was a button on the toolbar to run it without going to settings but thats okay. Please, please PLEASE recode this for firefox 57, because its one of the most useful and important addons in the addon database. Thank you again!

Does the job Rated 5 out of 5 stars

Finally a duplicate checker that does the job properly: finds duplicates and deletes them all, leaving just one valid link, en masse.

Needs to be updated for the 57+ FF

Excellent add-on! Feature request... Rated 5 out of 5 stars

This is an excellent add-on!

I would like to have an optional mode to be able to choose which duplicates get removed from which folders. Their tags and folder locations would be visible. See the legacy add-on https://addons.mozilla.org/en-US/firefox/addon/bookmark-duplicate-cleaner for an example.

Wow, super fast and super efficient! Rated 5 out of 5 stars

Worked like a charm and found 4000k duplicates. Not sure how that happened but it worked great.

Awesome ! Saved me from Burden Rated 5 out of 5 stars

+1 for its creation. It has saved my ton of time as used to import bookmarks from other browsers and duplication occurs. Last time, I have deleted 1775 BM using this one. Keep it updated.

Kindly add more features Rated 5 out of 5 stars

I have custom folder system to organize my bookmarks. This addon does not show from which folder the duplicate will be deleted.

Kindly add feature to select *which of the duplicate user wants to remove. Example: https://addons.mozilla.org/en-US/firefox/addon/bookmark-duplicate-cleaner/ (This add-on is not compatible with my version of Firefox. )

Does not work anymore, preference page unavailable Rated 1 out of 5 stars

There is no preference page available in the current verion of Firefox, so you can't use it.

Working just fine!
I'm missing a bookmarks menu item though. Great replacement for Bookmarks Duplicate Detector.

Funciona perfeitamente Rated 5 out of 5 stars

Muito prático, não precisa reiniciar o Firefox após instalar. Ajuda muito, pois eu uso o EverSync pra sincronizar junto com o Chrome e às vezes ficam favoritos duplicados.

perfect. Thanks a lot! Rated 5 out of 5 stars

Clearead no needs bookmarks.

Only caused Firefox to "not respond" Rated 2 out of 5 stars

clicking "Remove" only seezed Fiirefox v54.1. I really needed it work, darnit!

Worked for FF 52 Rated 4 out of 5 stars

Once I read the instructions to find the 'search' button under the addons listing, bing bam boom, duplicates gone. Very simple.

Superb Rated 5 out of 5 stars

This is one beautifully simple, useful and reliable add-on. Thank you.

Превосходно удаляет дубликаты закладок

Unbrauchbar Rated 1 out of 5 stars

Zeigt offensichtlich nur ein Duplikat. Aber nicht, wo er das andere gefunden hat. Somit hat man keine Möglichkeit richtig aufzuräumen. Ein intelligentes Programm zeigt alle Duplikatee und lässt einen wählen, was man löschen will!

ブックマークの名前やフォルダー名が表示されず、 URL しか表示されない Rated 2 out of 5 stars
