Shortcut to Fill Data on your web page

Number of time I have to login to the page, as it get expire soon. So I have added JavaScript shortcut in my Favorites Bar.

Writing this, maybe some one else is also facing same thing :) !!

javascript:(function(){document.getElementById('username').value='xz7xz8' ; document.getElementById('password').value='pwdxyz123' ; document.forms["loginForm"].submit(); })();
