How to enable auto-login (autofill) like LastPass

FYI, for anybody posting in support of this idea — here is the corresponding Feature Request, where you can cast a vote:

Automatically submit login form on auto-fill

Add an option to automatically submit login forms when an autofill action is performed. We might want an option to do this globally and/or on specific items. If we have a global option we would then also need an option to override it and disable it for specific logins too since the behavior may not be always desirable in certain situations.
