I did upgrade. I have Firefox 5 ,6 and (as of today) 7
I startet FF6 in a termina window and tried my internet banking logon.
The following error message was printed in the terminal window as 
Firefox closed down:

Error occurred during initialization of VM
java/lang/NoClassDefFoundError: java/lang/Object
