Why no FileSystem API in Firefox?
A question that I get asked a lot is why Firefox doesn’t support the FileSystem API. Usually, but not always, they are referring specifically to the FileSystem and FileWriter specifications which Google is implementing in Chrome, and which they have proposed for standardization in W3C.

multiple file input in Firefox 3.6
Firefox 3.6 supports multiple file input. This new capability allows you to get several files as input at once, using standard technologies.

Firefox 4 – FormData and the new File.url object
This is a guest post from Jonas Sicking, who does much of the work inside of Gecko on content facing features. He covers FormData, which we’ve talked about before, but shows how it can connect to an important part of the File API we’ve added for Firefox 4: File.url. In Firefox 4 we’re continuing to […]
