There is no stop function when searching through bookmarks, and you always have to scroll down to select them. This may be fine with a few hundred bookmarks, but with thousands of bookmarks it's annoying. You have to wait forever for the list to be processed. And Firefox's performance drops dramatically during this time. With a stop button, you could pause the search to sort through the results. But then the select button has to be at the top, because it always moves with the bookmarks found. Terrible!

404 Search should:
- note URL of bad bookmark in list generted
-search following order in the Bookmark tree in Firefox ...subfolder path should be shown

- bookmark title should be searched for within site as sometimes things are still there but located differently
-bookmark should be searched in Google (or other search engine) as it can sometimes still be found
-a csv list that can export bookmark name/URL/Path in Bookmark tree/Date added etc. would be helpful

The additional search features noted above could be run after the initial list is generated if this makes doing this easier

A variety of problems found

Efficient in finding the dead links, but while doing so, it produces extreme traffic that sends my ISP into red alert and into bugging me with recaptcha checks. Meanwhile, Firefox comes to a halt and crashes from overload. The hit list is not saveable, so there is no other way about it than starting all over again, and going into an into an endless feedback loop. Sadly, I have to uninstall it, though I have no functional replacement for it.

Пользоваться приложением неудобно, потому что нет индикации его работы, и доли сделанного от всего объема запланированных для проверки закладок. Кроме того, отображается название закладки, но не отображается ни путь к ней, ни ее адрес.

Hi, don't work for me with FF56.0.2, fix ?

A remove ALL button would be the BOMB but for now a fizzle...

Implementation in a panel is not a great idea since it re-checks all bookmarks each time you open it and the results don't cache. The list keeps scrolling to the top as it returns results so you have to wait until it's all done... and forget about viewing another website while it works since you have to start over if you leave the panel.

Cette extension aurait pû remplacer AM-Deadlink avantageusement. Je l'ai installé sur Cyberfox 64 bits dernière version. Au premier clic sur l'icône dans la barre, 404 Book m'a listé un paquet de liens morts sur les 4000 que je dois avoir avec une étiquette "remove" à droite pour chacun des liens morts puis Cyberfox a planté puis si je clique à nouveau je n'ai plus rien à part Cyberfox qui "gèle" plus ou moins. Cette extension est très instable et pas finalisée. Je conserve pour l'instant en évitant son utilisation.

I love what this add-on tries to do but the implementation is very poor. The list of bad bookmarks often disappears for no apparent reason. Plus, there's no way to copy the questionable link (using Cntl-C) so that you can check the site in another tab or browser. If these two things were fixed then the add-on would be way more useful and usable.
