I'm using 1PW 18.104.22.1687 with Win 7 Enterprise SP1 (64 bit) and IE 11, and when I go to a website and enter a login and pwd that is new to 1PW, I do not get prompted by 1PW whether to save it or not. The same thing with FireFox 50.1.0 generates a prompt to save or not.
1Password Version: 22.214.171.1247
