The FireFox version of this really sucks unfortunately. It is extremely buggy and has had basic functions broken for months now. When you click the tool icon which is supposed to give you a way to put the password on your clipboard, the icon just disappears and nothing happens. I have to go "edit" an entry just to get my password every time it doesn't autofill.

Which is another thing btw. A lot less things autofill than on Chrome.
