I knew that option, that is why I leave this comment. Uncheck both options(addons and toolbars), there are two addon icons shown in the "customize toolbar" dialog, please make it into one, which means the icon can only show either in the toolbar or the addon-bar.

Please do not do the user's job by place addon icon to tool-bar or addon-bar atomatically, It is not really necessary, many firefox users have their own favor of placing addon icons, also, by supporting this, you have added two same addon icons into the "Customize Toolbar" dialog, it is really annoying.
