Rated 3 out of 5 stars

they don't stay enabled all 4 of them whenever firefox restarts it defaults back to the original theme

This review is for a previous version of the add-on (1.0910). 

Thanks for your kind. This problem will be solved on the next updated versions (1.0929) very soon. You might need to remove all the existing SmallringFX themes and restart your browser first, then re-install them once the updated is available. Sorry for any inconvenience first.
