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).

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

Haven't figured out how to use it

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.
