Not sure how much help this will be but...

Have a look at the httpheaders extension, it can intercept all HTTP
traffic including headers.

Regarding the hung process, I experienced the same with
nsIFileInputStream, I noticed that if fileStream.CLOSE_ON_EOF is set
then you cant get the stream, it's needs to be
nsIFileInputStream.REOPEN_ON_REWIND to intercept the stream itself.
