why firefox doesn't have this attributes (http://www.w3schools.com/html/html5_form_input_types.asp) on this page ?
http://www.w3schools.com/html/html5_form_input_types.asp
from this page you will find some attributes for input types or input element
like : all date & time attributes ; search ; tel ; min & max ; step

This article has more up-to-date documentation on what attributes and attribute values have been and have not been implemented, and in some cases, some background on that: https://developer.mozilla.org/en-US/docs/Web/HTML/Element/Input#Browser_compatibility
This site seems to be a bit behind on Firefox versions but has test pages: http://www.wufoo.com/html5/
Are any of these attributes/types particularly important to your project?
