Fed up with Firefox - Passwords gone!!!

I'm fed up with firefox. It seems almost every update deletes old passwords or creates new profile (which effectively deletes the passwords!) I've tried looking at about.profiles which seems pointless - the active profile does not have my passwords and the inactive profile does not have them either. If you can't secure passwords what's the point of your browser?? I'm moving to another browser which can guarantee the security of my passwords. Meanwhile, I must visit every site I use to reset my passwords - what a chore!!!
