Not defined entity in preferences

Created by: cwesson

When trying to open the preferences this error message opens (translation in brackets):

XML-Verarbeitungsfehler: Nicht definierte Entität (XML-error: not defined entity) Adresse: chrome://linkalert/content/preferences.xul Zeile Nr. 5, Spalte 1 (row 5, column 1) :<prefwindow id="linkalert-preferences" title="&linkalert.title;" ^
