Hi list,

Did an update to firefox last night and rebooted over night.

Today I find firefox started without asking for master password - funny 
me thinks.

Try to log in to a web service I use and find that my password does not 

Check preferences and find that no master password is set and the 
password list / table is empty.

As I do not trust my passwords to the cloud I do not save these to my 
firefox profile ..... so back to manual entry for all my sites.... wow 
going to be a slow month as I reset scores of passwords.

Any one else have this problem and any clues as to what causes this? I 
am concerned if this should happen again, as I have saved passwords for 
many scores of web services.
