Very cool add-on.

One suggestion to improve it for the one that have a lot (lot) of bookmarks, and a certain series of duplicates. The possibility to show the created date, and to delete the newest or oldest of the duplicates. It allows to delete the bookmarks following the date we will keep.

Thanks for this great work !

Rapide et efficace

Nice, helpful FF Addon although it routinely marks a Folder of my Firefox 60 Addons as "All Broken". They All work perfectly. Addon/Save temporarily Removes Red Dot but Next Scan produces same, Incorrect Broken tag.
Manual Deletes a Must as Other Broken Errors exist that may Delete Desired Bookmarks.

All below Work - Show Broken ---

Shows Always as Broken. It works as all others do.

Working well on a large collection of bookmarks. I wish there would be a way to disable the confirmation dialog for each delete.

Works very reliable since version 2. Still getting some weird duplicates about built in items (place:type and place:transition), which is probably a data integrity issue in my profile/sync data.

Works very well on my 600+ bookmarks. Will rate 5 stars with whitelisting and ignoring redirects for keyword search URLs. Would also be nice if it differentiated 404s from connection resets.

Nice extension. One feature that would make it better, in my view, is a way to bulk delete duplicate bookmarks. Nonetheless, thanks for making it available.

This is a fantastic option for those that have amassed a huge amount of bookmarks over the years and just want a simple script to help clear up the broken links or verify what addresses need to be updated. However it doesn't allow me to reorganize where my bookmarks are, which I assumed would be an option with the name of the program. I'll be using this again though as it's still a very good option!

Its pretty useful, but my main issue is that there is no option to remove bookmark duplicates, en masse, leaving behind the first bookmark found, a la bookmark deduplicator. Its a real pain to be hunting down hundreds of possible duplicates one by one. If that feature could be implemented then you found yourself a permanent user!

Seems to work well, but I have some feedback:
1) Details about the error or warning would be great to include in the results. As it is I'm having to right-click each URL and open in a new tab to see what's going on.
2) Would it be possible to add an option users could enable if they so choose to update favicons at the same time?

Works for me on the current FF. One question - the 3 little green dots are always active? It makes me wonder if the app is never finished processing if they never stop moving.

As another reviewer was saying, things may work better if the dup check is done first.
If you check broken links first, it may hang.

Very intuitive. But took me a bit to get use to the large split screen. Only problem was I had to disable it to get back to normal window. Perhaps because I'm using an older version of FF (v. 52.0.1 (64 bit) on Win 10.

For some reason, it always recognizes https://transfer.sh/ as error.

I had written a review that perhaps wasn't fair and I apologize to the developer. I deleted the old one. This is a new review.

Regarding the scan locking up, I think if you have a lot of duplicate bookmarks, what you need to do is start by dealing with those before you have it look for dead links. Once I did that, it went much more quickly when looking for the dead links and it did complete the scan. This extension also worked to fix redirects and stuff. You have to look over each one because it did find some false positives, which is natural and I think it even said to be careful in the dialogue itself. Can't remember for sure, but just don't blindly click your way through this stuff.

I don't know how I had so many duplicates, but it would have been nice to have had a way to select them in bulk.

Thank You for perfect "Bookmarks Organizer" and for the operating answer. I ask You a pardon - at repeated starting was found, what, nevertheless, commands "Edit" and "Delete" appear at induction of the mouse for all items, EXCEPT FOR the first item. (What for with the mouse?). To tell the truth, hand-handling of hundreds items is difficult. It would be nice, if it would be possible to define an main-folder ("Collection"). It for READ-ONLY. And to check other bookmarks on secondariness in relation to a main-folder. Then by the additional command to delete automatically its duplicates from other folders. Forgive my unattention. Thank's.

!!! NOW IT IS NOT ACTUAL : (The script has checked up all mine 2783 bookmarks on doubles. Has detected 681 error. Now a green asterisk with three running points. And doesn't offer any further operations. The naked list in some hundreds items on which there is NO possibility of handling).

This extension looks promising (peculiarly to replace something like Bookmarks Checker, which is now deprecated).

The only important feature which is currently missing is the ability to select only one or more folders (rather than all the bookmarks as currently).

Moreover (although this point is minor), the new brand icon lacks of contrast and becomes virtually invisible with a slightly dark theme.

I run 2 machines 1 Linux Ubuntu 17.04, one 16.04.
The 17.04 ran well, however, it keeps spitting out links as redirects even though they are the same exact address. That's not a big deal, but I had to run it several times to get broken links completely. As for slow internet being a problem...thats not exactly right. I ran the 17.04 machine that had 1400+ bookmarks and it ran pretty quickly (did seem to hang on the last 20 though). When that machine was done I went to the other machine which has same internet connection and 1843 bookmarks and after 15mins it has scanned 15, so its not internet (I verified all was ok with my connection which is very fast). The only difference is that the machine that went fast is fairly new with 16 gigs of memory while the one that doesnt seem to want to get past 15 has only 4 and a slower processor. This tells me there may be a problem hogging memory. I hope this helps the author of this add on since I have been searching for something just like this for a long time. Thank you for your work so far!

Edit: I created a new clean profile with this add on as the only add on with the slow machine and imported my bookmarks and its working, so there must be a compatibility issue with other add ons
