I'm not sure what you mean. As far as I can remember, Firefox has had HTML 5 forms since Firefox 4 (https://developer.mozilla.org/en-US/docs/Web/Guide/HTML/Form...).

What exactly are you talking about?

[recursive]

It has some of the elements. It doesn't contain many of them, such as any of the date or time related ones.

I think he means these: http://caniuse.com/#search=input

Firefox doesn't support advanced (and more user friendly) input types. Number, color, date/time.

At least that's what I'm guessing.

I am talking about the rest of them. In particular, the most useful ones: date, time, datetime(-local), hell even number is useful and forever missing in firefox.

[shrikant]

The only form elements missing from Firefox (according to http://caniuse.com/forms) are the date/time, number and colour input types. IE only partially supports the number input type, and doesn't support the rest.

It's hard to believe you have to tell users to use IE over Firefox because of that difference.

Number is in Aurora, and color in Nightly.
