Small, Unglorified... and, no non-sence... This app does exactly what it says it will do.. NO BOOKMARK DUPES... It saved me a complicated mess of 1Million bookmarks being compound doubled due to Chrome Sync and a Third Party Sync app just getting it plain wrong. No Chrome extensions could fix my mess. Other Firefox extensions, LOOKED good but expected me to click on each bookmark to delete (Ya Right). This is the ONLY one that did the job, and did the job Right, with just the right amount of control to get exactly what i wanted back. Thank You Martin!

Amazing addon. Solved my years of problem that storing too many duplicate bookmarks! Works perfectly.

Fantastic program. Had been manually trying to remove duplicates caused by Xmarks issues months ago. Installed Bookmark Dupes and not long after it had removed 11293 duplicates. Very easy to use. No problems encountered so far either.

One star short. I would have liked to it merge duplicate folders.

Bravo, exactly what I needed. Removed 724 duplicate bookmarks and took a few mere minutes. Automatically pick oldest added duplicate worked for me.

After a Firefox account sync on a new machine, I was left with many duplicate bookmarks. This extension removed them, and then the empty folders they had been in, with just a few clicks. It took just a few moments. This was a great time saver.

Quickly handled 12,000 duplicate bookmarks caused by bugs in Xmarks

Highly recommended!

This extension is a COMPLETE WASTE OF TIME!! No sooner than I download it, I follow the instructions to the letter, and all I get is the instructions page of 'how to use this extension" I can't get anywhere with this extension!! Then I try the "support site", what a CROCK!! You have to SIGN UP for the gift hub account to even get into the support site, then there really doesn't seem to be any way to do THAT!! I can't get past the "create an account" page!! I may just have to go back to using Netscape or chrome!

Probably the best extension to remove duplicates at present.
