Please add an option to prevent the whole add-on from showing up in the add-on bar.
I like to customize the placement and order of the individual buttons in my add-on bar, so I have dragged each one of the buttons to my add-on bar.
But when I then try to hide each of the buttons that appear in the add-on block, it leaves a very large space.
Add-on bar extra spacing fixed in 188.8.131.52
When the new version is reviewed and released by the Mozilla team you should be able to "Hide" all of the status bar icons and they will not take up any space.
