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!

efectivo, rápido, intuitivo

Just brilliant! I have hundreds of nonsensical bookmarks that I am too afraid to remove, but this extension helped out with duplicates, empty folders and dead links.

You want sum 5 stars?

I had a lot of dead bookmarks and this cleaned them all up.
