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.

It has some interesting ideas for selecting duplicates, like checking all similar bookmarks from a folder, but it quickly becomes messy when dealing with many duplicates across different folders (might work for people with fewer bookmarks, I guess). Unfortunately, this extension has no progress indicator, so there's no way of knowing if [Merge duplicate folders], for example, is really merging folders or just crashing badly, consuming lots of memory and processing power (after several minutes of waiting, I had to restart Firefox and didn't find anything different from before using it...)

Finally I found a good addon for me

Install, press buttons. Done... mostly. Would recommend "Find broken URLS", , "Remove empty folders", "Merge duplicate folders", "Find duplicated bookmarks". The last one is understandably relatively manual as there is no way for the add-on to know which of the bookmarks you would like to keep.

Only thing I would love to see added is to have the dupes grouped when there are several dupes in the same folders. Maybe re-arrange the buttons to give better flow and maybe an auto button that does each task in the most optimal order...

But really, this is an awesome add-on and does what it says it does.

Genial, easy, sure and do what it correct. Thanks a lot!

Haven't figured out how to use it

Quick, but could not delete all-bar-one, which makes sense when you think about it. Not everyone is going to be wanting some kind of hesitant, multiple locations cautious approach, most are likely to have all in one location either downloaded from their cloud, or self-managed and moved over manually each upgrade-up.

And even-if one was wanting to filter by location, or other attributes, to deliberately keep SOME but not all of the duplicates found, there was no custom / fiddly filtering if you did need that.

A couple of parallel useful functions, like delete empty subdirs (subdirectories but not initial directory highest-level 1st directories, only 2nd onward) ... but one was then needing to ALSO delete the 1st level - one needed to manually find the USERS/ location for them anyway, to remove the highest level.

mm... program permissions? not asking for administrator confirmation? 1st level has runtime carried-over, passed-on executed BY user permissions, but subsequent do not, and are more easily reversed? something. not really a timesaver, when then unless you were OK with STILL HAVING most of the upon-1st-mouse-hover drop-down list (lvl1 depth) ... STILL being as clogged as it was before having clicked delete empty directories,.. but did want to say,.. ONLY reduce the number of extra directories for things like reducing the amount of empty directories on one's computer for shortening how long windows search catalogs user directories for the Index? sigh... then yeah, OK, some might find that useful,.. but coincidentally? The main POINT, of a duplicates manager/handler, should be for the VARIETY of reasons and needs, different people will be needing to do DIFFERENT, things, while doing that. i didn't ... i only needed to leave 1-of-everything ... but i also couldn't do that.

Essentially, the extras did not compensate for not being able to filter , sort, etc, nor select-all , nor in my case, select-all-but-1

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?
