I am trying to customize my dock. Having just downloaded the firefox browser for OSx, I wanted to place the fox on the dock.
Two strange problems. First, I could not drag the firefox icon to the dock. Starting from the MacHd/Applications folder in finder, the drag has no effect. I was able to get the icon on the dock with the shift-command-T keyboard combination, but no drags work from anywhere to put either applications or folders on the dock. Strange.
Second, after getting the icon to the dock I can't change its position. Dragging dock icons around just lands them back to their original position.
