I don't use Google, Facebook, Yahoo or OpenID. So I login to my new StackExchange-Account via the login-dialog of StackExchange itself.
Don't have an account? -> click here to sign up If you’ve forgotten or lost your login information -> click here to recover your account
Within Firefox I see a regular option for entering my login-data above this. It seems to me, that the necessary option/fields are loaded asynchronous after the other options and inserted at the top. But this fields are not loaded in Epiphany or Midori. With the official browser of Android (also WebKit) it works, but the mobile-website itself is designed in an other way.
What is wrong?
