Why does Firefox return 0 as the value of $(window).height()

Question

It seems to me that Firefox ought to be better equipped to return the proper value when using $(window).height().

I am using jQuery 1.8.2. Is this a bug

Answer 1

I found the answer to this strange render of height by jquery in Firefox...

I used class="no-js" in my html tag with doctype... when I removed this, FF calculated correctly... so I added this class with jquery like this $('html').addClass('no-js');

now the calulated is same in all browsers..
