How to skip Safari's "Do you want to allow this page to open X" dialog? I'm pretty sure I haven't changed any setting or installed anything other than software updates, but today I've started getting this dialog when I clicked a magnet link:



How do I get rid of this dialog? I've clicked okay once, but then I've clicked another magnet link and got the same dialog again. Why did it suddenly start and how do I get rid of Safari constantly asking about it?

I'm on macOS 10.12.2/Safari 10.0.2
If the application you want to use is already running (or is in the dock), you can drag and drop the magnet link onto the application's dock icon to avoid the dialog.

There's also a discussion on the Transmission forum on this. The dialog that appears when clicking on such a link seems to be a Safari security feature that currently can't be disabled.
