And by the way... for Opera users, there is a wonderful resource where you can create (drag & drop) special buttons to do 'almost' anything you'd want to do in a browser toolbar.
I have extra buttons to toggle various toolbars on & off (makes extra space)and to get new tabs......but there are hundreds (wow, they say over 2600) of choices (most of which are very special needs)...like controlling java, javascript, cookies.
