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

It's the only extension of it's type so I'm glad it exists, but a large percentage of the time when I log into my computer, it fails to switch from light to dark or vice versa. Wish it worked better, but glad it exists.

absolutely love it
