Laut Amo Seite wird die 501 nicht weiter entwickelt.
Mann sollte anstelle diese neue Version verwenden:
Multirow Bookmarks Toolbar Plus 1.0
https://addons.mozilla.org/en-US/firefox/…ks-toolbarplus/
Da ich diese Erweiterung nicht verwende kann ich dazu nichts sagen.
Ich verwende dazu die Erweiterung Stylish https://addons.mozilla.org/de/firefox/addon/stylish/
und dieses Script hier:
