Attached patch fix.patch (obsolete) — Splinter Review
This is an existing bug in PBlob implementation but it's shown only removing this dataTransfer bit (related to nsContentUtils).

When a remoteBlobImpl is sliced, if GetInternalStream is called on a different thread, the inputStream is not sliced at all.

fix.patch

I don't understand this and neither will whoever reads the code later. 
Why is the sliced input stream needed? Why it is needed only in
} else if (PBackgroundChild* manager = mozilla::ipc::BackgroundChild::GetForCurrentThread()) {
case?

This needs some good comment, explaining both those questions.
