Comment (by cypherpunks):

 There's something broken with the "Save Link As..." contextual action, as
 well:
 * It, also, ends up over the catch-all circuit.
 * Furthermore, "sometimes" Tor Browser's custom "Save external file type?"
 dialog is not shown, instead Firefox's "Save As" dialog is shown directly.
 When this happens, after confirming said "Save As" dialog, the download is
 not started ("nothing happens", as they say).  I have not yet discovered a
 reliable way of reproducing this but it's not rare, it occurs after trying
 a few times with random links.

 I have not (yet) seen these problems occur when following the link
 instead.

 Tor Browser 7.0, security level set to High.
