Details
It would be convenient for me if these were exposed as real constructors. Currently I'm grabbing references to them from a DOM window, but that feels less than ideal.

For XHR there's a simple workaround as explained at https://developer.mozilla.org/En/Using_XMLHttpRequest#Using_XMLHttpRequest_from_JavaScript_modules_.2f_XPCOM.c2.a0components Being able to use just new XMLHttpRequest() instead of Components.classes["@mozilla.org/xmlextras/xmlhttprequest;1"] .createInstance(Components.interfaces.nsIXMLHttpRequest) would be nice, but I don't think that it's a big problem. But for FormData I don't know of any workaround, so I would change the bug to deal just with this issue.

Well, I'm able to create both interfaces via createInstance. It's just not ideal.

And what's the code to create a FormData? So far I haven't been able to find any documentation about that. Thank you. But if you can create then with createInstance, why did you state that you are "grabbing references to them from a DOM window"?, that forces your code to get a reference to a window that you wouldn't need otherwise

After reading the original patch I've found the implementation, so this seems to work: var formData = Components.classes["@mozilla.org/files/formdata;1"] .createInstance(Components.interfaces.nsIDOMFormData); Now I just need to find how to do new File(path);
As of Firefox 8 you can just do "new File(path)" in a component.

(In reply to comment #5) > As of Firefox 8 you can just do "new File(path)" in a component. Thank you, that worked. Any chance of having some code (even calling some weird code like that .createInstance) that works in 6 or 7? (I'm really liking the fast release cycle and being able to use such new features and fixes without waiting years)

Probably not, precisely because of ... > (I'm really liking the fast release cycle and being able to use such new > features and fixes without waiting years) Indeed. It's awesome!
