had several all-but-one functions, ugly, but worked. just what i needed, without all the faff.

perhaps dated code, did not delete empty directories, however. found them, but then something couldn't get through perhaps windows protections,.. not sure. sat there at 0% complete, no errors, no pop-ups, no consent-on-the-desktop, etc. Might need a few code updates, but the CORE NEED, of being able to combine future searches for a individual bookmark regardless of where AMONGST your mess of directories, after you've removed duplicates,.. for a minimal-effort combination of the two,.. i could do. Good enough. Thanks!

This extension has been a lifesaver after a particular synchronization app duplicated my bookmarks in exponential numbers. There do, however seem to be a couple of glitches. I'll forward more detail to the developer...

If it gets Hungarian, you will get the five stars! consider it necessary!

Den gør arbejdet men ikke specielt hurtigt eller kønt

Good tool for fix URLs or fix parts of the URL, but on complety dynamically generated URL for static website content it fail.
e.g. searching for jobs on https://jobboerse.arbeitsagentur.de.
but this could be solved with saving with unique strings (reference-number) on the website.
Then this duplicates could be found with replacement the dynamic parts of url and a filter ofexpression for name and URL.

now my summary of things good and bad:
(+) very performant
(+) very mighty filtering with regex to find duplicates
(-) it is not very inituitive , a complete debug log in a text file or browser should be usefull
(-) the combobox and the regarding Button are not intuitiv to, a quick improvement could be put the combobox and reagrding butting in a border toshould that it belongs togehter
(-) if no special filter fits or deep subfolders it could be in some case it could confusing , show only bookmark name on the link could help (switchable: Full path bookmark name / short bookmarkname)
(-) i think the the system of local and sync storage is not so good. better where a default profil and create some profiles if the user need and a combo-box to use the filters of the of the selected profile

Feature i really miss is following:
- If I look or filter for duplicates i often would rename a bookmark but then go in the bookmark mangemnet or dive in the subfolder and use the context menu to change to properties is very elaborate.
- export / Impo settings
- creatable and selectable profiles for different filter settings

If thsi feature will implemented i will give 5 points

It's a very good add-on to find dupes & empty folders. The other 2 options are kinda useless or I just don't understand their purpose! Why would I want to see non-dupes or all bookmarks? I could do that through FireFox!!

This reduced 47,000 bookmarks to 7,000 very quickly. Thanks! The only reason it isn't 5 stars is that I still have to merge some folders by hand. Would be good to have a way to find folders with duplicate names and an offer to merge them. But a great add in all the same!

Does the trick. The UI could be made better, but it's bare-bones and does what it promises.

One star short. I would have liked to it merge duplicate folders.

Mooolto bello, mooolto semplice da usare. CONSIGLIATISSIMO. Da migliorare la grafica per la quinta stella.

Firefox 67.0a1, Windows 10. Нельзя выделить сразу все найденные результаты, приходиться выделять по одному. Пустые папки находит, закладки с одинаковыми URL тоже.

Bookmark Dupes removed over thirteen thousand* duplicate bookmarks in about ten minutes. The multi-select is awesome. Remove all but the newest, for example.

My only regret is that it doesn't *seem* to support merging the contents of folders with the same names. After deleting empty folders, I have two hundred folders remaining with various different assortments of bookmarks in them, but most of the folder names are duplicated over five times :)

*-(Some people might be wondering how I ended up with so many duplicates to begin with. Xmarks and to a lesser extent Sync had some problems merging bookmark sets with large numbers of changes between different computers. A few browser crashes while syncing didn't help. That led to huge amounts of bookmark and folder duplication.)
