hi, as i read this, its complicated this way. pls inform the developers to make it easy: 1. to remove via : about : config or 2. to drag it to : customize toolbar .it should be easy and as another member/nino4/ says:it would be nicer to have the option to remove it. for who is this software - for the developers or for us- the users?

The developers won't take any notice of me. However the more of us that express our displeasure at https://connect.mozilla.org/t5/discussions/bd-p/discussions the more chance there is of something being done.
