This is an amazing pulgin which has fixed my browser's bookmark bug.

There´s a lot of false positives. When the list is finished, you must start checking one by one to see if its really a deleted link or not. It needs lot of working.

Would be even better if there was options to select multiple duplicate webpages. To help save you time manually deleting them all.

Easy to use and intuitive. Not found any errors. (October, 2018)

It was only supposed to clean out the broken links (as that was all I selected) and it ended up removing ALL my Facebook bookmark links. So I am removing this. I seriously wish I had been as smart as reviewer of this addon Scott750 who did not let it delete but checked the bookmarks it wanted to delete first only to realize that the ones that were supposedly dead bookmarks actually were not. I wish I would have read Scott750's review before u sing this addon. I sincerely regret using this extension.

If it can show why the bookmarks are considered as error, e.g. 404, 500, or network error, it would be better. And the other thing is that the paths of duplicated bookmarks are not complete, I couldn't decide which to delete since they usually in two different but same name folders.

Developer did a good job, this extension works well. I got rid of over 300 dead links and even more duplicates.

Helpful in spotting & managing duplicates. Helpful to further screen errors & warnings in more detail.
