Assegnate 5 su 5 stelle

Easy to use, convenient. I have been using for several years. I just had to back out of FF 57 and retreat to previous version so I could retrieve my credentials. How can I copy (cut and paste, export, etc) the credentials to another system? I don't know how long one would have to wait for this add-on to start working with quantam FF or if one is even notified that a new version works. I don't want to be caught off-guard again!

You can still access your passwords, just a bit less conveniently.
