Now at http://protips.posthaven.com/cdff-cd-to-the-path-of-the-front-most-finder-window
I'm getting a error:
execution error: Can’t make «class fvtg» of window 1 of application "Finder" into type alias. (-1700)
Nope, it's always just worked for me. Sorry! If you find a solution please post it here and I'll update the tip.
