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).  This user has a previous review of this add-on.

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.
