How to delete duplicate bookmarks?

I have a lot of duplicate bookmarks in Firefox and the number keeps on adding on. There are few answers regarding this on Support pages but none of them work. Neither the add-ons mentioned there(sad such trivial and basic things need add-ons) .

As there's no good way to sync Chrome and Firefox bookmarks I often end up manually importing in either browser from the other and after that I end up having tones of duplicates. I can deal with this in Chrome but have not figured out how to do this in Firefox. I think Sync ought to handle this.

Anyway, any quick solution regarding this? Preferably without an add-on (sigh!! one more thing to slow down the browser).

Firefox doesn't allow duplicate bookmarks to be saved. A user can override that feature by copying a bookmark to a different folder, or by saving a "dupe" bookmark manually, by dragging the "dupe" to a different folder from the original.

I'm not sure how Sync handles duplicates, as I have so many "dupes" from the days before Firefox 3.0 when the saving of "dupes" was removed from the "Bookmark this page" button and menu items.

As far as "importing" bookmarks from another browser, Firefox will import duplicates.

Sorry, the only way I know of finding and deleting duplicate bookmarks is via an extension. Bookmark Duplicate Detector was the last extension that I used, in years past.

Yes. But the extension doesn't work anymore. Not on the latest FF.

Try this extension:

Thanks @cor-el. Worked like a charm :-)

I installed the checkplaces-2.6.2-fx+sm.xpi add-on (Thank you, cor-el) and used it to delete duplicate bookmarks. Unfortunately, I don't think you can rely on all the checks the add-on performs. The results showed many "failed" pages and other errors, but when I actually tried a few of the "failed" bookmarks they still worked. So, use at your own risk I guess.

It is possible that there are problems with the places.sqlite database file if you get such errors and that there are no real duplicates.


You can check for problems with the places.sqlite database file in the Firefox Profile Folder.
