Multiple file uploader in HTML5 — browser support?

Question

I read that the HTML5 spec introduced the ability to select multiple files in an upload form. What browsers currently support this? Does Adobe AIR support it?

Bonus

Answer 1

Opera has supported this feature since 2006.

Answer 2

Chome developer builds now support this attribute! :)

Answer 3

Firefox 3.6, soon to be released, will have it as well, along with some other file-related goodies:

It is also supported by Chrome 3.

I have no info on Adobe Air, but it might be so, since the feature has been in Webkit nightly for more than a year.

Answer 4

afaik Safari 4 is the only browser that supports this feature. I dont know about your other questions.
