Hier nun der komplette Code.
Die von mir eingefügten Kommentare sind jetzt nicht so das Gelbe vom Ei,
aber besser als nix.

}Meinst du das so?
Wenn ja, dann teste bitte:
CSS#placesList treechildren::-moz-tree-row(current) { border-radius: 16px !important; }
Oh, so geht das auch? Ja, so meinte ich es.
Was ist nun "besser", selected (ausgewählt) oder current (aktuell) 
Wenn es mit beidem geht, ist aber current (aktuell) wohl treffender (bezeichender), oder?

Es geht
