  • Works perfect :)

  • DESERVES 10 STARS IN MY OPINION!

    I went from 9451 bookmarks to 1412 in 5 minutes. How I did this:
    1. clicked on bookmark dupes on mozilla taskbar. (The double star icon).
    2. clicked on "Dupes" in the extension (the first {leftmost} of the 3 boxes).
    3. Skipping the box marked "Remove marked bookmarks", which believe to be in the wrong place [IMHO]
    I clicked on the "Mark all but the last in each group" (Choises are first, last, oldest or newest)
    4. went back clicked on the box marked "Remove marked bookmarks"

    Result 8,039 duplicates deleted.

    Just had to delete the empty folders and I'm your uncle.

  • It does what it is supposed to do. Fast and simple. No ads or over-complication of simple things. Has many options to ensure you can keep the bookmarks you want without a headache. A good guy made this I am sure.

  • Exactly what I needed !

  • An excellent extension! It worked even better than I hoped it would.

  • this is too perfect to be an extension, thanx martin vath for writing this piece.

  • Excellent! Easy to use and remove all duplicates easily!

  • Hi, Martin,

    Unfortunately, I couldn't make the extension work.

    If you describe the problem in more detail, maybe I can help.
    However, I suggest to discuss this either by private mail or on the github bug page, since this medium here is not appropriate for a conversation with successive questions + answers.

  • love this <3

  • I managed to inadvertently duplicate my entire bookmark list by exporting it as html, then inadvertently importing it back into Firefox instead of the target web browser. This extension saved me from hand deleting 1188 duplicate bookmarks and 66 duplicate folders. All I had to clean up was a few bookmarks that I had added after the duplication occurred to one set of folders, but not the other. Great Plug-In!

  • Fantastic! I was able to clear up duplicated annoying bookmarks in a few seconds!

  • I had a bookmark duplicate remover/cleaner/deplicator, nothing worked like this without headaches.
    Really impressive.

  • This is a really powerful, efficient and easy to use tool for organizing bookmarks and killing dupes that got scattered over time. If you've collected a bunch of bookmarks - like the 2,000+ that i have - this tool is invaluable for getting your stuff back in a pile. Great job, Martin!

  • Very useful. You can mark by folder or rule.

  • It does what it says.
    Thanks.

  • Funktioniert perfekt!

  • Works very well.

  • This is just perfect.

  • Super. Mehrfach gespeicherte gleiche Seiten in allen Lesezeichen finden, markieren und löschen.
    Danke ;-)

  • Worked well... Recommended

  • Tut genau das, was beschrieben wird. Einfach in der Bedienung, klar im Aufbau, jetzt herrscht wieder Ordnung in meinen Bookmarks.

  • Fantastic tool. Everything is automated and has great filtering options. recommended for cleaning up your bookmarks.

  • It works and is the best deduplicator!

  • Worked perfectly. Used the basic functions to find and delete all my duplicate bookmarks.

  • To difficult to use. A waste of time. Might as well delete the bookmarks one at a time.
