Your browser does not support javascript

[KIRIN178]

Hi,
I found that Google blocks the script at function signIn
$mink->getSession()->getPage()->find("css", "#Email")->setValue($email);
$mink->getSession()->getPage()->find("css", "#next")->click();
I did getContent and got the error message from google, which said "Your browser does not support javascript. Please enable javascript for your browser."
Do you have any idea of this error?
Thank you very much!
