hi jimbo3108, i am sorry for this issue - as it looks at the moment this happens for a small number of users with an unforeseen configuration, probably triggered by a preference set by the Norton Identity Safe addon. firefox developers are working on a mitigation for that problem as we speak, but unfortunately that can not help after the fact, when passwords are already lost.

do you have any form of backup of your firefox profile or your harddrive in available? if so, we can assist you in recovering any password data from there...
