EDIT: Devs fixed the issue I mentioned, thank you so much for updating it! I love this theme it's my default Firefox theme.

I love the theme a lot, I just don't like that for vertical tabs when you're not in an active window (e.g. you have 2 windows and you're on window 1),the inactive window's vertical tab color would be blue compared to the active window (window 1) which is black. it's quite distracting and this does not happen when vertical tabs are off, but I love keeping my vertical tabs so I hope you could fix the inactive vertical tab window to be black instead of blue! thank you!

my fav of all times thank u sm

i love you this theme is perfect
