Firefox 54.0.1 (32-bit)
I had this issue before and it just seems to be returning with every new update. I click the button and the "Where to save files" dialogues did pop up, however, it is now only pointing me to the default "Downloads" folder. This feels a little pointless as it used to remember the last location that I saved certain file types to. Then, I tried to update it, just in case. It only worsened the issue and now I don't get the "Where to save files" prompt at all.
This is becoming very frustrating. How is it possible that it works just fine in previous versions and now it suddenly bugs out?
To confirm, I have enabled "Always ask where to save my files" both in my browser and in the settings.
