hi guys,

    I am currently involved in a online assessment project. The system as of now does not allow its users to change windows as soon as the assessment window us loaded. Changing windows was detected through the window.onblur event, problem is that on firefox, onblur  doesn't fire when current focus is on an input tag with type text. I have tried so many workaround but none of them perfectly works.

Hope somebody could help me. I am stuck for two days with this bug  

Try using addEventListener:

if(document.all){
    document.getElementById("myframe").attachEvent("onblur",dothis);
}else{
    document.getElementById("myframe").contentDocument.addEventListener("blur", onBlurHandler, false);
}

function onBlurHandler() {
  // handle onBlur in Firefox
}
