The expected behaviour of Safari when clicking on a, for example, .torrent file, is that it is downloaded.
Only this does not happen any more, it just shows a dark, blank page
The only way to download the .torrent file is to right click the link to it and select "Download linked file to 'Downloads'".
It should probably be worth noting that these problems started when I added GreaseKit to Safari, but I would very much like to keep GreaseKit enabled. Is there some other way to fix Safari?
