Why don't you allow the icon to be moved? Rated 3 out of 5 stars
I don't know if this works, & I guess I won't until the option to move the icon to where I want it to be is added. I don't use the add-on bar, & so the fact that I can't move the icon off of it basically means that it's useless to me. It's always so disappointing when developers neglect to give users that option.
