exactly what i needed, thanks

Working great. That's exactly what I was looking for. I love it. Thank you.

Perfect

More than just time-based : This one's actually can sync with OS settings, so it helps cover one of Firefox's drawback. Very well done, light, and responds quickly.

Can you add option for changing dark and light modes by data from css: prefers-color-scheme: dark.
Thanks!

Thank you so much for making this, this is something I've wanted for ages
