Rated 5 out of 5 stars

You did a fantastic job! It is great that you made both Thunderbird and Firefox themes. They are a nice couple again! I work with a simple and clean interface that give me a fuzzy nostalgic feeling, but at the same time I know I work with totally accurate and up-to-date software.
I feel sad for the Apple users though. It would be perfect if they could enjoy all of this beauty to.

This review is for a previous version of the add-on (0.1.2). 

Thank you for your feedback. Is it not possible to use the Linux version for Mac Thunderbird? I have heard of people using the Linux version of Orthodox for Firefox on Mac OS and it seemed to work.
