Rated 5 out of 5 stars

Works fine, just have to configure your locaton, and where to put it's icon. This add-on works for both 'Firefox' and 'Thunderbird'. Just hover the mouse over it's icon, and you'll get sun rise/set data, or whatever you have it configured to show.

It's 'Display Placement'(?etc...?) doesn't take effect until the close button is clicked, and it doesn't have 'Apply', 'Cancel', nor 'Ok' buttons, it just has a 'Close' button.

Don't know what 'azimuth' means, so I can't say anything about that.

This review is for a previous version of the add-on (1.3.20120620.1-signed).
