Please unhide browser.download.start_downloads_in_tmp_dir and add it as an option on our main Settings page.
I've noticed for awhile that files I've opened to view were being automatically downloaded into my downloads folder, but I haven't investigated it until now. I found out this goes back to 2022! My downloads folder is cluttered with files I only wanted to view and not save. On a previous thread on the Mozilla Support forum, I found that a new hidden setting was added so we could change this back to the old behavior of the automatically-downloaded files going to a temporary folder instead of being saved in our downloads folder. We can use about:config to find browser.download.start_downloads_in_tmp_dir and toggle it to "true." (The files are then deleted when we clear our history, which is normally when we close Firefox as long as that is in our settings.)
Instead of our having to dig around on the forum to find how to change the automatic downloads, the setting needs to be added to the Main settings page under "Downloads." Then those of us who wish to "always" be asked where to save files will be able to find this setting and change it to our preference. If I want to download something to keep, I will intentionally save it. If not, I expect anything I read online to remain in a temporary cache folder and be deleted when I clear history (which is when I close Firefox, because that is what is selected in my settings).
Again, please unhide browser.download.start_downloads_in_tmp_dir and add it as an option on our main Settings page. Thank you.
