Rated 5 out of 5 stars

Great theme. I just wished, I could use smaller icons in the Mail and Composition Toolbar (in Thunderbird).

This review is for a previous version of the add-on (3.0.1). 

Thanks.
I haven't the time to work on this option when Noia Fox 3.0.0 & 3.0.1 will be posted, but small icons option will be added in a future version.

Sorry, but there is no support option available, so I hope it is ok to report a problem here.
Since 1.3.0 the close button on the tab is not on the right side anymore. It is somewhere around the 2nd third of the bar.

This review is for a previous version of the add-on (1.3.1.1-signed). 

Tab close button will be placed on the right side in the next version.
