Rated 5 out of 5 stars
For those who don't speak Chinese, this addon puts all of your addon bar's (status bar) icons in the urlbar (not the toolbar!), effectively replacing your url if you have a lot. It then hides your addon bar giving a little more screen space. However, the urlbar will be a bit bigger (the same size as when large icons are turned on.) He also says to turn off the icon text through your customize-toolbar options.
It displays EVERYTHING that the status bar does including notifications and download status. Works well with Status-4-Evar addon (or statusbar options for Palemoon users.)
