I have Windows 10 and I love the colours for this theme! It's a gorgeous blend! But there are no options to change tab settings in Firefox (that I can find anyways) to make tabs a different colour or NON-transparent. Consequently, the text of the tabs and favourites bar is very hard to make out and too small, against the bright coloured background of the theme.

I just got it literally 2 minutes ago and I haven't even surfed yet but from what I see I LOVE it. Nice job guys.
