Unfortunately I cannot find anything helpful on your homepage. The link is being redirected to http://www.ndparking.com/serve.php?lid=538167&dn=cutemenuproject.com&kw=download+firefox&fn=7067950375
And there I can only find sponsored links, but no help for this extension.
So: how can I add missing icons, where do I find explanation for the settings options?
