This tool is fantastic. I have almost 2k bookmarks, and trying to de-duplicate and find old, dead bookmarks by hand is a huge pain. This add-on was able to identify several hundred bookmarks I could prune and made it easy to fix broken bookmarks I wanted to keep and remove dead bookmarks. Thanks Sören!
Bis jetzt funktioniert alles bestens, Firefox läuft rund, sehr praktisches AddOn, endlich mal Ordnung im Lesezeichen-Dschungel. Manche schreiben vom Ordner, der nicht gefunden wird?! Ähm, Mozilla-Ordner suchen und gut ist.
First it needs to scan, then, in the results not shows the full path of bookmark(s) but it shows them at second scan, then, you have to delete unneeded bookmarks one by one(!), then, I needed to refresh (scan again) and then not working, It freezes.
