I am bummed out. Firefox still hasn't implemented the date picker that was in the HTML 5 specs that came out a few years back.
I hold that the date picker should be provided by the browser because it gives the client a unified experience across sites. Here is a sample form with the new HTML date types. Chrome and the other browsers I tested have date pickers. Firefox does not.
This means I can't depend on the feature. Arrrggggggghhhhhhhh!
