FF6 Support Rated 4 out of 5 stars

Still a great theme, but on FF6 I have lost the switches (replaced with plain icons) and I cant get the icons to colorize.

This review is for a previous version of the add-on (4.1.1). 

Switches

You are most likely in small icons mode. Got nothing to do with the theme. Just go to "View" --> "Toolbars" --> "Customize..." and deselect "Use small icons".
