Firefox on Mac Sequoia

Still loving this theme, but there are times when I need a light theme, so in firefox I need to change "my" much beloved nyan theme.
It would be cool if there was a lighter Nyan cat theme too.

On chrome broweser I switch to "system"and
Mac OS System varies foreground/background by time of day/night.

This theme goes perfectly with my goal in life of making the world a better place one cat at a time.Nyan Cat and this theme makes me smile. The Smooth Jazz Nyan Cat mix on YouTube is my favorite :)
