Very usefull one. And good use of boostrap 👍

Work extremely well for removing bookmarks with broken links. Great addon. Can quickly remove dead links, empty folders and duplicate bookmarks

I love this, and want to make a feature request, please add a progress bar, I can't tell whether it is working or not.

Works great

Из подобных расширений по работе с закладками это для меня оказалось лучшим. Корректная работа, ошибок практически нет

Nice and clean user interface, one extension that save time and do exactly what is intended to do ! Many thanks author.

The best

Simple and easy way to clean up the bookmarks. Find and clean duplicates, merge cuplicated folders and manage broken links is easy to do wiht this extension.

Super. Macht genau, was man erwartet. :-)

Super easy to use.
Worked great.

It would be nice to see the title, or where in my bookmarks the offending bookmark is located, for future improvement.

4 -> 5 stars: Just cleaned close to 5k bookmarks (that I sync on Firefox between 3 devices) with this add-on. Updated a few ones I still need and deleted the rest, all-in-all took me 15'. The check took less than 30', during which I worked on something else.

2020 review:
- this add-on correctly detected quite some dead bookmarks that '404 Bookmarks' add-on had not seen in this location. So very good.
- Dupes it detected were actual *folders*, so deleting them would have brought havoc in my bookmarks library. Not good.
