moderated Re: How to get to the save password dialogue in firefox
That feature is on by default, and the dialog should be presented unless you've turned it off.
See the Mozilla support page: https://support.mozilla.org/en-US/kb/password-manager-remember-delete-edit-logins#w_managing-usernames-and-passwords and head for the section on Disabling the Password Manager, where, of course, you can do the reverse to re-enable it.

Tolerance is the positive and cordial effort to understand another's beliefs, practices, and habits without necessarily sharing or accepting them.
