It's slow down so much it makes frozen the app. It's waited for10 minutes without any response. It's just about 16000 -24000 bookmarks to process, certainly from several bookmarks from different times.
Interesting fact is the same addon from the same author works perfectly!!! ..in chrome based browsers(time to response fast to not:chrome,brave,vivaldi).

works pretty fine for me

Good extension scans all your bookmarks well but is there a way to export your cleaned bookmarks.

Simple mais suffisamment complet

Отличное расширение. Очень простое.

Excellent extension, very helpful for work!

very good, easy to use.

Great, it did what it said it does.

It works if you know how to read :P

It works.

The only thing I learned about this add-on is that it lives up to its name. (itwillnotbeeasy) Installed, adjusted settings, and nothing. No start, go, launch, proceed, remove, engage, button to do anything. Uninstalled, reinstalled, used defaults, still nothing. No way to make it work. PLEASE HELP

Works well, but a search functionality would be great for those who have thousands of duplicates, like me :(

Fantastic Extension and Exactly what I needed!

Does what it says pretty well. Strange choice to not include a 'Select all' for the duplicate finder, but you do for broken URLs. I get you want us to keep one item remaining, but what if I don't want any of them to remain? As someone who needed to manage close to 5000 bookmarks, this did well enough.

(Updated) Seems to work well. Rather difficult to find how to run it though. Perhaps the dev could add the instructions to the 'Description' or 'About this extension'?
