Rated 5 out of 5 stars

Love this theme, myself. I have it working with TB 11.1. However I have Mr Tech Toolkit and Add On Compatibility Reporter, so I don't know if either of those is helping but from what I understand starting with FF 10x (and TB 10?) they are making add-ons auto-compatible b/c of the rapid version changes. So you shouldn't need Mr Tech or ARC.

This review is for a previous version of the add-on (3.36).
