Ok, I’ve found the issue for FF, and the updated code is posted to GitHub.

I can’t figure out how to change Bookmark URLs in Safari/Win, and I can’t get the drag-and-drop working properly, some conflict between a crap-load of JS inside an <a> tag’s HREF, pushing all that through WP, then trying to drag-and-drop into a Bookmark, causes a conflict, go figure… :-)

But at least you can get it working, with just a little added effort…

Thanks,
Atg
