Gibt kein besseres Addon, als dieses hier, tut was es soll! Danke.

Great add-on! Really cleans up and in a modern and usable fashion

Great extension! Congratulations!

thanks for your reply
i checked again and found two things:

1.
some working links were only reported as broken when the tracking protection in Firefox (disconnect.me / basic protection) is on; i know it was stated to set it of, but i thought since v.2.x the add-on would take care of that, sorry my fault
(just for info, these were some of the links: http://statcounter.com/ ; https://www.forbes.com/ ; http://www.ip-tracker.org/ ; https://twitter.com/ ; ...)

2.
still, with tracking protection off, there are some other working links reported as broken; it seems to occur when a site redirects to a localized version
(e.g.: bookmark = https://www.seagate.com reported as broken, but it opens https://www.seagate.com/be/nl/ ; also bookmark = https://www.microsoft.com/nl-be/default.aspx reported as broken, but it opens the same link) ; (note: a second run gave the same result)

hope this helps, thanks again for this very usefull extension, 5 stars now

========

about a month ago i had problems with the add-on hanging at the last bookmark check(s); all fixed now in version 2.x, works like a charm (also fast: 1600+ bookmarks scanned in a few minutes)

4 STARS ! (only reason for that one star less is that some working links are reported as broken (e.g. twitter) but i understand some false positives are nearly inevitable 'cause site settings, etc.)

big thanks to the developer

works like a charm

Version 2.0 works like a charm.
Remember (if the API allows it) the reload favicons feature. :-)
Thanks.

ff59, plugin v.2.0.
finally all troubles fixed, works as intended.

Genial, al acabar muestra de manera muy fácil los marcadores con problemas y su posible solución.

Great! when it finishes it show in an easy way the bookmarks with problems and an easy workaround to fix it.

very useful addon for me and works fine here with Fx 59beta, it founds all duplicate and invalid Bookmarks, great work!

Perfect for cleaning up my bookmarks

Very good addon and very good design !

The only lacking features:
- an option to be able to disable the http to https redirect warnings.
Because I use an automatic http to https redirector (extension : Smart HTTPS), so all HTTP urls are in Warning...
- a new functionality to be able to list the empty folders

Brilliant addon. Makes it so easy to correct redirects, remove duplicates and to edit broken links. Have patience it does take a while to finish checking the last few bookmarks.

Great

I'm a tab girl, so I can bop back and forth between screens and not lose the page I was just on. This works exactly like I want to have everything right in front of me! THANK YOU! **NOTE** This review is for "Open Link with New Tab" add-on...my mistake!

THIS EXTENSION WORKS FINE!....

I read a lot of complaints here about slowness or freezing, but decided to try it anyway.

I opened it up via the toolbar button and started the process of checking "broken bookmarks."

The extension found 11,348 bookmarks (total) and checked them - at a pace of about 1,000 per minute.

Then, when the field "Checking Bookmark Number" reached bookmark # 11,290, it seemed to stop counting up (freeze?), but the activity throbber was still moving.

Unsure, I went into developer tools and checked the activity, and saw that the page was not frozen and the extension's script was still working.

FYI: I use 2 PCs on my desk, so I turned my attention to my other PC and did some things on that one. About 10 minutes later, I turned back to the PC with this extension running and lo and behold, the "Checking Bookmark Number" counter had ticked up to bookmark # 11,292.

Realizing it was just gonna take some time for the "problem child" bookmarks to be checked, I let it go overnight.

This morning, I found the extension had completed it's job and I was able to delete duplicates, remove broken links and edit others, all right within the results window (tab).

The process of editing is a bit slow (one at a time), but I'm sure the developer will attend to that in good time.

All-in-all, well done. Thanks to the developer, we now have a bookmark checker for 57+ and we'd not had one for years!

Great job, developer!

It helped me to clean up my bookmarks and reduce their number by one third.

Does anyone at Mozilla really WORK with Firefox bookmarks and use more than 10.000 bookmarks ?
How do you find the folder of a result URL after searching ?
How do you jump to the folder of a result URL after searching ?
Now that Go Parent Folder and Show Parent Folder (alice0775) are omitted, for power users Firefox is almost as useless as Chrome.
Concerning the ancient bookmark user interface, why should anyone use Firefox instead of Chrome ?
Sorry for being off topic, should not explain colors to the blind.

I uninstalled this in 2017 because it didn't work as expected. Following the developer's suggestion I've tried it again today and it appears to be fixed. It's found over a thousand errors and two-hundred and thirty broken links, and it's fixed them all in a flash. I'm happy to change my review to five stars for an excellent add-on.
