Does exactly what it says on the tin! Extremely useful Add-On. Thank you. :)

What a uniquely POWERFUL addon! It works VERY WELL INDEED! I can't figure out why strings I place into the "Name Matches" or "Url Matches" fields affect the resulting list not at all.

I'm intermediate at regular expressions and I do understand the intended effects of the "filter, modify or does not effect the search" radio buttons, but these seem to have no effect. Why are my attempts at filtering not working?

It would be great if we didn't have to refresh the page and could have a big fat: APPLY CHANGES BUTTON to quickly test various attempts at filtering.

Thank you for the hard work that went into this fantastic and helpful bookmark addon!

Needed a way to remove duplicate bookmarks caused by who knows what, sync going haywire? This worked pretty well. Thank you.

Grate!! Thanks!! It's exactly what I need!!!

It does the job. That's essential, since other bookmark managers doesn't have (even though they should) that tool.

This addon does what it should, has lots of options, but most importantly, it allows you to define the deletion rules along with which bookmark folder to apply them on, which other extensions don't do. This allows you to delete duplicates in just about any way you wish.

For example, you can remove the duplicates only in one folder that you specify, or you can select the folders in which duplicate bookmarks will not be deleted, while deleting them everywhere else. Very useful.

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.

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