Question : Does anyone use a password manager to keep track of passwords, which one do you like?
I have been using a password manager for some time now and I’d like one that is integrated into firefox. Mine now does not do this and it takes a few clicks to get the username/password plugged in. Any recommendations?

Not safe to use a manager. Its like a cookie jar full of passwords.
