Rated 5 out of 5 stars
Extremely useful... this should be included by default on Firerox. Has Mozilla expressed such desire to the developer of this wonderful addon?
Just for existing and working well it deserves 5 stars. It's not perfect but it's on the right track. It's even better than the official implementation on Chrome/Chromium. For example, if you click on a notification it will switch to the tab that generated it, that's a wonderful and desirable behavior that I still haven't seen on Chrome/Chromium.
Keep the good work...
