An almost prefect extension Rated 4 out of 5 stars

I'm giving this 4 starts instead of 5 because while it does EXACTLY what I wanted it to, it doesn't support notifications higher than 999. Need to take a cue from extensions like Better GReader, or the greasemonkey scripts that it employs, and created a catch all for over 999, something like 1K+ would be ideal. Other than that admittedly tiny nit pick, this is a top notch extension.

Another request for next version, if you could allow adjustment of the txt size when it's over the icon and not next to it that would be great too.

This review is for a previous version of the add-on (1.8.1-signed).
