Comment:

 I can confirm this. I originally posted to #22616 but it seems more
 appropriate here.

 The problem for me is concurrent downloads. First download always works
 but trying to download another file at the same time always fails with
 this:
 {{{
 unsafe CPOW usage forbidden
 contentAreaUtils.js:466
         continueSave
 chrome://global/content/contentAreaUtils.js:466:1
         internalSave/<

 }}}

 Mac OS 10.11.6 with Tor 7.0.6 (64bit), and also 7.5a8
