It was good and has served it's purpose Rated 5 out of 5 stars

Worked well and brought a much-needed functionality to Firefox. http://code.google.com/p/ff-html5notifications/One would think this is bad news, as this page indicates the addon has been discontinued. I will miss it. However, HTML5 notifications are now integrated into Firefox, so why would it be needed? It's good in a way that it's discontinued. It means Firefox has matured on open HTML5 standards.
