FormData is quite a bit more complicated now than when we first implemented it. We should enable the new features.

Jonas, should I hide these methods behind a pref?

I don't have an opinion on FormData really. I haven't been following it lately.

That said, it seems to me that FormData is growing into a generic holder for a list of name-value pairs. Which is something that JS already has in the form of plain JS Objects/Arrays.

Would it be possible to come up with a syntax for fetch() and onfetch that doesn't requre FormData objects at all and that instead uses some other mechanism to indicate that a given JS Array should be multipart/form-data encoded when it's sent to the network?
We had that discussion before. JavaScript doesn't really have anything like a multimap. And FormData already has the integration with HTML forms and XMLHttpRequest.
Ok. Like I said, I haven't followed this very closely so I'll defer to others.
Jonas are you still going to review this considering you were the original author? Otherwise I'll pass it on to baku since he has done most of the File work. Pref or no-pref?

if you use File everywhere you don't need this static_Cast

I don't like this int32_t. What about this (I didn't test this code):

FormDataTuple*
nsFormData::RemoveAllExceptFirstAndGetFromDataTuple(const nsAString& aName) // invent a better name please
{
  FormDataTuple* data = nullptr;
  for (uint32_t i = 0, len = mFormData.Length(); i < len;) {
    if (!aName.Equals(mFormData[i].name)) {
      ++i;
      continue;
    }

    if (!data) {
      data = &mFormData[i];
      ++i;
      continue;
    }

    mFormData[i].RemoveElement(i);
    --len;
  }

  return data;

Then, here you can do:

FormDataTule* data = RemoveAllExceptFirstAndFoobar(aName);

do you need this .get() ?
