Rated 1 out of 5 stars

This app is good for monitoring when your folders get new messages. After all, you don't want to have to scan all your folders to see if you have a new message.

However, if you get lots of email, like when you start up Thunderbird, you might get a dozen notices. The first 11 disappear in less than a second, so those messages are as good as lost.
It would be a lot better if a list of folders were displayed, and you could click to dismiss certain notifications or click to jump to that folder. The key is to be notified of all the new messages in the folders I choose.

This review is for a previous version of the add-on (0.16.4).
