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

Excellent! Easy to use and remove all duplicates easily!

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.
