User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:56.0) Gecko/20100101 Firefox/56.0
Build ID: 20171003101344

Steps to reproduce:

The browser.downloads.download() API allows to specify the HTTP headers that are sent along with the request. However, this follows the XMLHttpRequest.setRequestHeader() restrictions. For instance, it is not possible to set the Referer header.

Although having those restrictions on Web page-callable XMLHttpRequest service is perfectly appropriate for security reasons, having this limitation on add-ons is too restrictive.

This causes for instance the Video DownloadHelper add-on to fail downloading from many sites because the server expects a specific referrer that can not be provided by the add-on when requesting the download.
