It doesn't work with Thunderbird 31.0 anymore.
Error:
"XML-Verarbeitungsfehler: Nicht definierte Entität
Adresse: chrome://folderpane/content/folderpanePref.xul
Zeile Nr. 263, Spalte 19: <menuitem label="&filemessageschoosethis.label;"
------------------^"
Also the open tabs are closed after a restart of Thunderbird.
