Quick Cut quit working for me too, saving only as HTML. I tried earlier Quick Cut versions, they don't work either. I appreciate the developer's explanation so will use as is for now. Have appreciated Quick Cut very much through the years, worked like a charm.

I have set Mozilla to save to the desktop as default and also to prompt for location, so I get a dialog box that allows me to edit the url and location.

If I save without editing the name the link works with no warning. The security warning appears only after i rename the shortcut.

The file save dialog box should default to *.url as opposed to *.*

Not clear why I can not edit the saved URL but can edit the ones I drag to the desktop. Not yet clear if it's useful if I loose the favicon and need to accept the security warnings. Rather a bit more work to set up something I will frequently use to work and display right.

It works perfectly well, all the times, every time with every site.
Problem, it doesn't show the site favicon.icon on the Desktop, it shows Firefox boring url shortcut icon on all of its desktop shortcuts, so if you have 25 URL shortcuts on your desktop and everyday you delete and add few here and there, you can see it becomes very problematic. You can't figure out which shortcut belongs to which site without highlighting it or clicking on it or activating it, a total waste of time.
P.S. The older DeskCut has same problem, it doesn't preserve the site favicon, only SaveLink works to perfection but alas not compatible with Firefox Quantum.

The options for this extension should include a default folder (like, I don't know: the desktop !!).
Starting to sound familiar?
What's the problem with adding it to the right-click menu?
