It was good and has served it's purpose Bewertet mit 5 von 5 Sternen

Worked well and brought a much-needed functionality to Firefox. 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.
