Problem with Samba 3.0.10 + Roaming Profiles + Citrix + Firefox Application

[Roman Hudelist]

 We encounter Problems with a certain Configuration: 

Roaming Profiles on a Samba Server (Samba 3.0.10) accessed via Citrix 
Firefox behaves in two ways: 

1. Firefox opens but hangs showing a white window 

2. Firefox opens normal but if you open an extension, it tells that a File from the Firefox-Profile could not be found. The Dialog shows the Path to the File, but it is too long to see, where it is pointing to. (I guess its pointing to the extension-Directory {9....} something. In Addition to that it shows a white frame in the background which fills the whole screen. 

i wonder how this problem may occur only in combination with loading the roaming Profiles over Citrix from the samba server. can anybody help pleese! THX!
