Comment (by sysrqb):

 Replying to [comment:8 sysrqb]:
 > Within scenario (1), Firefox cannot know what it should do without
 beginning the download. That's okay. With scenario (2), that is completely
 against what the user requested. This is almost certainly a Firefox bug,
 unfortunately it seems Firefox handles (1) and (2) using the same logic.

 Hrm, and this is related to #22649 (coming from #25672). But, to clarify,
 it may be that #22649 is resolved if "Save Link As..." does not use a
 speculative connection. If it uses a connection created within the context
 of the current first party domain, then maybe the download will use the
 correct circuit.
