Firefox 52.0.1 (32-bit). Helper version 6.20. Helper doesn't ask where to save files anymore.

Files are automatically downloading to the default folder and the helper is no longer asking where to save them. I have checked my settings in my browser and "Always ask me where to save files" is enabled. I cannot find any option like this in the current version, or if it is there, I must be missing it. Please fix this issue.
