Firefox on strict policy

[Ken]

I am attempting to get a strict policy working on my FC-6 system 
(version 2.4.3-2.fc6).  I have successfully created a user account,  and 
I can log both the root and the user account into the GUI.  I am 
attempting to get Firefox to work and I am having difficulties.  If I 
click on the Firefox icon, I see the program listed as opening, and it 
stays that way for a few seconds and then disappears.  If I check the 
message log (var/log/messages), there are no messages (either avc or 
other) generated as a result of the attempt. This only happens when the 
policy is enforcing.  When the policy is is not enforcing, Firefox loads 
properly -- also with no messages.  I have noticed that Firefox is not 
writing to its .mozilla folder when the policy is enforcing, and that it 
does write to several files in this folder when it loads properly.  This 
problem affects both my user account and the root account.  Can someone 
please explain why I am not receiving any error messages (or any 
messages at all), and let me know what needs to be changed in order to 
load Firefox?
