jesup, I'm not sure if you're the right person, but any suggestions are welcome :) Thank you.

Crashing inside of mozilla::net::HttpChannelChild::ContinueAsyncOpen() (while doing IPC things)

This is an xhr trying to upload a stream that is not serializable. XHR could be changed to call nsIUploadChannel2::EnsureUploadStreamIsCloneable(). This would also ensure the stream is directly serializable.

For some reason to I can't load that minidump in Visual Studio.
