We can probably make these arrow functions when I land my patch first :)

[Wladimir Palant, 2014/07/11 07:15:54]

Don't think so, arrow functions are for trivial functions - here I'd prefer
having proper ones.

-          for (let attribute of this.overlay["abp-toolbarbutton"].attributes)
-            node.setAttribute(attribute.name, attribute.value);
-          if (!node.firstChild)
-            for (let child of this.overlay["abp-toolbarbutton"].children)
-              node.appendChild(child.cloneNode(true));
-          if ("addClass" in defaultToolbarPosition)
-            icon.classList.add(defaultToolbarPosition.addClass);

           this.updateIconState(node.ownerDocument.defaultView, node);
         }.bind(this),
         onClick: this.onIconClick,
         onCommand: this.onIconCommand

These two lines don't actually do anything, they are ignored if type isn't
button. https://hg.adblockplus.org/adblockplus/rev/245083285e39 fixed this.

From the rest of the code it looks like this can be null, but I can't say if it
could happen here.

[Wladimir Palant, 2014/07/11 07:15:54]

No, it cannot - nothing would call toggleToolbarIcon() if the toolbar icon isn't
supported.

       CustomizableUI.addWidgetToArea("abp-toolbarbutton", defaultToolbarPosition.parent);
