I seem to have a issue using Firefox with Version 5. There is a little key emblem(left over from V3) in the menu bar along side the little key lock emblem of version 5. I can seem to get rid of that little key(v3) and when I try to open a login from version 5 the little key opens a window that wants me to reenter my master password. Everything with Safari works the way i expected. I trashed V3 but maybe there is a file left over that I don't know about. I have installed V5 extensions in Firefox.
