Bokkmarks closeKantu true but kantu windows remain opened

I use this bookmarks, it works but at the end of macro do not close Kantu Window

I see closeKantu true in the javascript


Why kantu windows do not close automatically ?

I use firefox ESR 60 (it’s firefox 68)

NOTE: The %20 was added by deault from firefox when i save the bookmark, in original was space " ".
