It's good but it's hard Rated 4 out of 5 stars

It's working good but it's hard to understand about something and find something.
- What is threads?
- It's hard to find where is the folder of that link.

In some case, I just found dead link but just want to modify URI not remove that bookmark. I have to know where it is and go to modify it directly.
It's hard to do that because there are bunch of folders here and I must find it one by one.

Boa, Good! Rated 2 out of 5 stars

Extensão boa, mas falta informar onde está localizado o favorito, isso dificulta muito você marcar qual dos duplicados apagar, como tenho muitos favoritos, a extensão para mim neste caso se torna inútil.

Good extension, but lack inform where is located the favorite, it makes it very difficult you select which of the duplicate delete, as I have many favorites, the extent to me in this case is useless.

Does not work with Pale Moon 25.* Rated 1 out of 5 stars

That add-on looks great, it seems to work with the latest firefox versions but not with Pale Moon 25.*. On Pale Moon, I get the "Nothing to scan" error, even after selecting all bookmarks folders manually. The link provided for this problem here on the add-ons page does not work.

Right-Click "MAXIMIZE" so you don't lose your mind with a 4" window environment. Rated 4 out of 5 stars

And that is why I took one star off. I had to fiddle around deleting items in my Toolbar to get it to show up. Reboot a couple of times. But yes, it does a magnificent job once you can get that little star to show. Duplicates, Broken links, Error-generated links. It's all there.

In addition to the primordial hack of "Maximize Window", it can be squirrely to page down while marking your entries for Whitelisting. Just click the lowest box, unclick it, line down once . . . and then you can "Page Down" until the next bottleneck. Repeat, Rinse. Others have noted the interface is in desperate need of some | | | columns | | |. I have a strong suspicion the interface was designed for a cellphone environment. Nonetheless it's a little beast, so BACKUP YOUR BOOKMARKS first. ;)

And if your monitor supports it I can tell you it's a thing to behold on a 1920px widescreen pivoted to Portrait Mode!

Awesome Rated 5 out of 5 stars

Really glad I found this addon. Had some issues with firefox and had to re add my bookmarks which of course created so many duplicates of each other. I love that this also checks for errors and bad links.

Rated 4 out of 5 stars

Works really well at finding bad bookmarks. However, I have three suggestions:

1. Make the report window resizable. This would reduce the need to scroll so much.

2. Make the column headings in the report window resizable too (after making the report window resizable). This would allow more information to show.

3. Add a location column. I arrange my bookmarks in folders and subfolders. Finding a bad bookmarks is still pretty difficult. I know I can delete a bad bookmark without having to search it down, but this would still be a useful feature to have.

Exactly as advertised. Worked perfectly the first time. Went through 3000 bookmarks in only a few minutes

Not too helpful Rated 2 out of 5 stars

Very needed add-on, but unfortunately very inconvenient solution. Once the check is done, it's not possible to edit URLs from the result list, or even see the location of bad bookmars, so correcting them is a nightmare. Also the bookmark library would be a better place for accessing the interface than the toolbar button (you don't need it very often).

Rated 5 out of 5 stars

Works like a charm, does exactly what it says.
Can also find duplicate bookmarks, which I also found immensly useful.

Why didn't try this before, I missed it Rated 5 out of 5 stars

Most awesome! Over the years I've accumulated about 4k bookmarks, and that's with using some web link checker tools. I've installed this and gone through it's results of my bookmarks, which was a lot more efficient than checking them on the web page I made of them. After going through the results, I decided to delete 99% of the bad results. Some I'll probably have to find again and will but most were links I knew I didn't need. This culled about 1k of links, some I've accumulated probably over 10 years ago that just redirected or were domains now for sale.

В окне результатов не хватает отображения имён папок в которых лежат найденные не рабочие закладки или дубликаты.
Также хотелось бы чтоб дополнение имело функцию обновления иконок сайтов для закладок.
Спасибо за Ваши труды.
