I have been using Firefox's built-in screenshot taking capability for years now and love it. However, since I purchased a new macbook air a few months ago and installed Firefox on that device, I notice something strange. When I go into setting and change the default location for Firefox to save downloads, the screenshots I take still end up being saved to my desktop instead of the download folder. On my old Macbook pro that I had been using for >4yrs this was never an issue.

I have tried resetting this but it does not seem to work. Any idea what is the issue?
