Comment:

 We could disable range requests easily in pdfjs but that is affecting
 rendering speed with unknown impact. Thus, this is no great idea to do
 without testing at least in one alpha. Fixing the root cause of the
 problem, an extension issuing XHRs and thus having no window associated to
 the channel, is no option for an untested stable patch either. Therefore,
 removing this issue from the 4.5 radar. :(
