Hi! I have sync enabled to sync bookmarks, addons, and preferences between computers. Recently I changed the theme on a single computer and only want that theme on that single computer. If I restart the browser on another computer it uses that theme, which is not desired. How do I modify my sync configuration so my active theme is not forced to all other machines I want to sync with, but still sync all my addons and preferences? Is this even possible? Thanks for your assistance!
