NEVER got beyond the blue spinning circle. I have turned this thing on look for duplicates and the fukkn blue circle was spinning the next morning, all the while not doing shit.

(typically, i can see no way to contact the developer. it is a complete mystery how to do that. i simply see no tab, button, option, for Contact.)

on this app, very simple and critical problem -

it is busy saying HUNDREDS of my BMs had a faulty link (w/o saying what), but when i decided to test a few that it had marked as a faulty link .... those links opened up perfectly happily on the link page

if i had been lazy and/or careless, i could have just deleted thousands of my BMs (when it had finished scan) that actually WERE NOT FAULTY.

how pathetic is that?

It seem to be stuck on "loading"; won't do anything.

E' inaffidabile!!! trova molte pagine con errori e ti dice di cancellarle, pero di solito il sito esiste e funziona bene, è che la pagina è stata spostata! così cancelli la pagina pensado che non esista più! inoltre non ti da la possibilità di aggiornare le pagine che sono state re-indirizzate!

This tool doesn't do anything. I can see the duplicates myself, thousands of them, but it doesn't delete them. No help or instructions anywhere that I can find including on the tool's page itself. One hour of time down the drain. I obviously can delete these dups one at a time but I have thousands that occurred recently so I was looking for a solution.

At times, I deliberately use the same bookmarks for different things. I KNOW that I have duplicate bookmarks. Yet, it found none.

This add on lacks instructions how to use it. Backup instructions are not enough. I tried to make this work but no success. I have at least several thousand duplicates including duplicate folders etc. It found not one duplicate bookmark.
