Where's the "Star button"?

Esta valoración es de una versión anterior del complemento (1.0a1). 

The star-button has been sorta replaced by the bookmarks menu button. The button should change depending if a site is bookmarked or not.

You can force it to show by adding this to userChrome.css or Stylish

#star-button {
visibility: visible !important;
}
