The download manager appears to be using a SystemPrincipal in the channel that actually downloads the remote file: https://searchfox.org/mozilla-central/rev/39cb1e96cf97713c444c5a0404d4f84627aee85d/toolkit/components/downloads/DownloadCore.jsm#1905
Jonathan, I think francois is right, that URI can potentially be influenced by web content. Can you take a look if we can use a better triggeringPrincipal?

Marking as a duplicate of Bug 1507773 as that work is needed to fix this one line.
