It is a bookmarks checker. I have to delete duplicated bookmarks manually.

Works really good, look nice, just the pop-up warning should be able to be disabled

Excellent extension - I've had many bookmarks for 10+ years or older. Extension quickly identified the ones no longer working - duplicates and redirects. My initial bookmark count was 2119 now 769. No problems whatsoever with the extension

Good to detect broken links, and duplicates, but useless for organizing bookmarks. I didn't have any problem with the bookmarks analysis (almost 300 bookmarks checked quickly).

Got stuck after having analysed all my bookmarks for several hours.

So ein tolles Helferlein! Da mußte ich doch mal gleich die Spende anklicken. In der Hoffnung, daß Bookmarks Organizer bald von Mozilla als "Empfohlen" qualifiziert wird. Und vor allem eine Art Whitelist updaten!

Tuyệt vời mấy cái bookmarks hồi xưa còn dùng http giờ dùng ứng dụng này sữa lỗi redirect link nhiều trang hiên tại lên https hay đổi tên thì sữa link rất tiện

Works very well. Interface is easy to use.

The function of this Add-On is difficult to automate because testing all those sites mechanically is going to set off countermeasures. Plus, where cookies have been deleted, the client is going to recognize gateway portals as a failure to load.

I give it 5 stars, but I do recommend that you implement check boxes for batch whitelisting because you're always going to get a lot of false positives.

Kudos.

EDIT: I just noticed the filter boxes at the top of the tree. You might still simplify whitelisting, or allow filtering entries as you go. Still, no redundancies or procedural anomalies. 5/5

Nice one

Finds fairly well all errors and duplicates but it's simply horrible trying to delete all of them. Uninstalling fro FF

Дубликаты находит, сломанные закладки ищет плохо, много ошибок. Полностью доверять этому расширению не стоит
