X-Notifier was the best extension for Firefox and version 3 was the absolute pinnacle of its abilities.

But I'm not even sure what is the point of 4.0:
It allows you to add multiple accounts for different services, but you're only able to log into the one that is set to default!
If this version no longer supports Scripts, why is there still a "Script" option to add to your account list?
This version is just so badly done, I'm not even sure if it has even gotten to the beta stage!
