All is right on FF4 with post 2 del.iciou.us Rated 5 out of 5 stars
@DeeBlueAngel is right this now works perfectly. No dragging to the bookmark toolbar (which I don't like to have open). Looks and works just the same as the previous plug-in.
I didn't even have to do the second step she mentioned. I just installed it and it appeared in it's former location.
