How to set default (current date) and display date format placeholder in Firefox?

[sjordan1975]

I created a fiddle https://jsfiddle.net/sjordan/r81k8240/

In Chrome the placeholder "mm/dd/yyyy" is present.

In Firefox it is not. Also, in Firefox, the calendar input does not pop up.

Also, I tried to use the "set" property (but no success) to set value to current date. How do I use "set"?

You will find more information about this by reading this issue #231
To put it simply, Firefox is not yet compatible with the native <input type="date">. It has nothing to do with us. As you can see, it is also not compatible with IE and Safari.
Read #231 for more info.
