It is a very helpful instrument to manage possible duplicates in bookmarks.

good

does delete dupes, but I can see no way to organize the remaining bookmarks. So you wind up with tons of duplicate folders and no way to delete dupe folders and organize remaining bookmarks.

Saved me so much work! Outstanding!

Saved me few days and removed over 18k of duplicates. Thanks a lot!

I had imported a large file of bookmarks, more than 350 and in multiple folders. Many of those folders were also duplicated.

While it took some time to click check the boxes, I now have clean and tidy list where all URLs are filed appropriately.

Thank you to the authors of this extension.

(Um ... I did look at the Expert option and realised that my HTML was not up to that!

I don't know what people are complaining about.
It worked perfectly the first time I tried it!
All doubles removed!!!

When I used the "select a folder" button, nothing happened. After trying several times, I just pressed the general "Dupes" button. Then I had to manually deselect many bookmarks that I wanted to keep, after using the "mark all but oldest in each group."

All seemed well... I walked away, as it was going to take a while to delete my over 4,000 dupes. I came back only 10 minutes later to see that the app crashed after deleting only 222. It said something like... some function was pending.

I restarted my browser, closed other programs and I set it up again. It crashed again before 200 deletions. What a waste of time.

The only reason, I'm not giving it one star is because the buttons let you custom search your marks to delete. The extension "Bookmarks Organizer" is the worst, where you have to delete each bookmark manually, and sometimes it doesn't give a great description of the path, so I ended up deleting useful marks. This one is better than that one.

My search for a good bookmark extension continues. Why are there so many good reviews in the past year? Deceptive.
