This is a terrible addon, I need to download whole directories and this stupid thing opens an OS file browser and makes you click 'save' for EVERY SINGLE FILE!!!! I am trying to download a directory with over 12,000 individual files. This implementation is MADNESS!!

Tried this in Firefox Developer edition. But clicking the button, nothing happened.

I did find another addon "Simple mass downloader" could do what I needed.

dosent work
