Works well if you set a default folder for downloads, but if like me you want to be asked where a download should be saved, then Firefox will ask that for EACH file simultaneously like an idiot, a popup nightmare and an astounding bad user experience. What are you thinking at Mozilla!?

RESPONSE 1: When I tried to download image links on a page with 32 images, it DID opened simultaneously 32 prompts, a nightmare. After your response I even tried with a fresh Firefox profile (no add-on, no setting) with the same result. Then I even tried with different settings and I think I found the problem: You may have overlooked the Firefox settings. By default Firefox is configured to ask where to download files, if I set a default directory then nothing is asked. But I (and many others) certainly don't want to use an add-on that force me to change the way I manage my downloads, so you definitely need to change something, like ask for a folder in that case.

RESPONSE 2: Thank you for your response. I have seen Mozilla do a lot of dumb moves, but throwing away its successful extension ecosystem to build a crappy API that can't even download a file properly makes me die a little inside... Well, I think I will need to switch for another browser to find what I need if the API is so badly designed. I will update my review. Thank you again for your efforts! :)
