Out of curiosity, has Mozilla already shipped a product that has the "uploadprogress" event?
Not yet. It's been present in development builds of Gecko 1.9 for a while, but not in anything shipped.
I suspect we'll just remove it in favor of the new setup, but wanted to make sure I knew what our options are.
Is it used by web content, or just by chrome/extensions? How widespread is the use?
I don't really have good data on this. I suspect the answers are "just chrome/extensions" and "not very widespread", but that's just a gut feeling, combined with the fact that it's not shipped and not yet clearly documented.
