Not everyone is happy! I downloaded this extension. I expected it to show up somewhere obvious (I'm not real computer saavy). Eventually I right clicked on a page and found "GDirections" on a little menu. When I ran my mouse over "GDirections" an empty little box appeared. When I moved my curser into the box, little blue lines appeared and when I clicked on them, a random new tab appeared.
So...I can't really use "GDirections", and I can't get the blasted thing off my "options?" menu.
Can anybody help me with this?

This review is for a previous version of the add-on (1.1.1).
