Simple but useful add-on

This add-on is very useful. Notifies new emails immediately. The only problem is that whenever I install a new add-on that adds an icon to the navigation toolbar, the gmail notifier icon disappears. I have to retrieve it from the customization window every time.

This review is for a previous version of the add-on (0.2.6.1-signed). 

This problem is solved on version 0.3.0
