Rated 3 out of 5 stars

First, thanks to the author for this nice addon.

It works flawlessly and as expected with thunderbird (enables to keep the app loaded all the time, shows the count of unread emails)

However, I wish it could be used with firefox in order to keep all the time one instance loaded.

I don't really understand the current behaviour. For instance, when ticking the second option, whenever a new FF windows is opened, it hides instantly all the FF windows. It would make sense if it only occured with the first one.

An option that would be useful, in my opinion, would be the following one : in order to keep one FF window always open, when closing the last FF window, it would be only reduced (and reopened when clicking on the tray icon). The former windows would be actually really closed. (ATM, it's either all of them or none of them)

It could be useful for people who wish to continue using it the same way as before, by reducing at the same time the loading times (when quitting / relaunching FF). (OSX behaviour actually)

This review is for a previous version of the add-on (0.2.3).
