Doesn't work on firefox

Hi Alfgago

The date picker is a HTML 5 date picker – so any browser that doesn’t fully support this will not render it properly.

It is entirely possible to add your own jQuery based date picker to work with this field (http://tjvantoll.com/2012/06/30/creating-a-native-html5-datepicker-with-a-fallback-to-jquery-ui/)

Alternatively this is built in in the pro plugin.

Thanks
