Attached patch patch v1Splinter Review
I had basically finished this patch by the time that I found bug 590682. That being said, I don't think we need to block redirects to data: URIs on such a generic mechanism. This patch is larger than I'd like because the HTTP redirect stuff basically assumes that we're going to need a channel in the parent as well as one in the child. data: is probably the only protocol that doesn't need this (and redirects to data: are probably quite rare), so I don't think that adding a little more code here is a terrible thing. Jason, let me know if there's a better reviewer for this patch.

You would need some IPC (at least placeholding) for data: anyway - even when we would create the target channel asynchronously on child (and let parent connect). The thing is that on the parent there are checks made on source+target channels whether to redirect or not. But these need to run on the content as well. So you need some mirroring here. @@ +39,5 @@ > + NS_IMETHOD OnDataAvailable(nsIRequest *aRequest, > + nsISupports *aContext, > + nsIInputStream *aInputStream, > + uint64_t aOffset, > + uint32_t aCount) MOZ_OVERRIDE MOZ_FINAL; why not use NS_DECL_NSIREQUESTOBSEVER and STREAMLISTENER?

I checked in latest Nightly Build ID 20150701030207, both in e10s and non-e10s . In both case the page is blank for me.
