You can execute the JS code after body onload event. Difficult to know exact reason. Post minimum code to reproduce the issue. –Subir Kumar Sao Feb 19 '14 at 7:58 1 How can we provide 'the solution' to a problem we can't see? We need to see the relevant HTML. –David Thomas Feb 19 '14 at 7:58 I suspect that Java Script code may be completed before form gets loaded.

Have you done any research suggesting that document.forms[0] is problematic in window.onload in FireFox? You are more than welcome to provide a bug fix as a pull request. See https://github.com/KentorIT/authservices/blob/master/doc/Contributing.md Kentor member albinsunnanbo commented Mar 5, 2015 I have trouble reproducing.
