Hello,
Actually, we did that for purpose, because the new password is generated by Adaxes automatically. How would users know their new password if it is masked? Of course, they can click on the eye button to view the password in the hint, like in IE8, but what's the difference if they need to view the generated password anyway?
As for the difference between IE8 and other web browsers, IE8 has been developed quite a while ago, and sometimes it is impossible to achieve the same behavior as with newer browsers.
