[Samba] Samba + Roaming Profiles + Firefox Application

[Roman Hudelist]

Dear Samba Comunity!
 I encounter Problems with a certain Configuration, please help!

Concerns: Roaming Profiles on a Samba Server (Samba 3.0.10) 
Symptom: Application Firefox behaves strange and crashes after installing an (any) Extension:
 
The plain Firefox Application without Extensions installed just works fine.
but after instlling an Extension, logging out and in again, it opens and hangs showing a white window.
After reopening it, it works again, but the former installed Extension has vanished.
 
I wondered whats happening with the files in the roaming Profile: 
During the Logon-Session were i installed the Firefox Extension everthing works fine and the Profile shows up the Extension-Files:
 ..Mozilla\Firefox\Profiles\ospucvhc.default\extensions\{34274bf4-1d97-a289-e984-17e546307e4f}\install.rdf 
..Mozilla\Firefox\Profiles\ospucvhc.default\extensions\{34274bf4-1d97-a289-e984-17e546307e4f}\chrome\adblock.jar 
..Mozilla\Firefox\Profiles\ospucvhc.default\extensions\{34274bf4-1d97-a289-e984-17e546307e4f}\install.js 
..Mozilla\Firefox\Profiles\ospucvhc.default\extensions\{34274bf4-1d97-a289-e984-17e546307e4f}\nsAdblock.js 
(they also exist on the Samba-Server Share, althoug i thought, these Profile-Data is downloaded locally to the Client)
 
after logging out and in again, under the same Login Name, these Extension files have disappeared (magically) from the server.
I wonder whats going on? can it be, that this is a Firefox BUG??? or is it possible to have a samba problem here? - all other Applications are working properly in this domain..

Logs:
I traced the log.smbd on Log level 5 (thousands of lines..) but i coudnt find anything suspicious..

can anybody help pleese! THX!
