Rated 3 out of 5 stars
I tried 220.127.116.11 with Firefox 18.104.22.168 (FF upgrade=downgrade! ;)
Drag/save images works with that option enabled but my FF already does that.
Re feature: "A URL will be saved instead of opened in a new tab if the Alt key is held while dropping."
Alt+Drag link fails to save link target:
When I Alt+Drag a link (to an image) I want saved, text is selected from where I click on the link to the window edge + nothing is dropped.
The only option enabled is "Use drag/drop to dl images".
