This is used both when the FormData contains a Blob, and when it contains a File with an empty name. In firefox you can currently get a file with an empty name using an experimental canvas.mozGetAsFile(name, type, ...) API, though this will eventually be changed to canvas.toBlob as has now been specified. But I suspect we'll end up with other APIs eventually which can end up producing files with empty names (I kind'a think that BlobBuilder should have a getFile(name) function for example). / Jonas
