Close filedilaog with truclient

A am using LR 11.52 TruClient for Firefox to record a opening a filedialog
(native) and chosing a file and adding it. Recording With Firefox do not
close the filedialog, but doing the same With IE Works (at least so it
sems). But when I run this script in loadmode/on the Controller With
several users I suspect it to create a memoryleak, because after some time
it starts to fail.
Is there a way to manually say to 'LR 11.52 TruClient for Firefox' that it
must close the browser after adding a file. Maybe java script on the
Object?
My script gets recorded With this action:
Set [path] on [object] filebox with an Object role of filebox.
