I checked about:config, but I didn't find anything related to the temporary folder.
By default, when you choose to open a file instead of save it, it would download the file to `/tmp', and open it when completed, now I'd like to pick another location.
Already tried to add browser.cache.disk.parent_directory, but that doesn't seem to work for 16.0.2
