Unfortunately doesn't work on the Old Reddit (old.reddit.com), where this add-on would be more useful, as Reddit's new UI applies dark theme automatically based on the browser settings.

Good extension! You should also make it work on the old.reddit.com domain since for most people, www.reddit.com will display the newest interface.

I've opted out of the Reddit redesign, and it still works. Awesome work, thank you.

Causes vote-icons to become invisible for me, making reddit harder to use. Not recommended.

Dev updated it, It works great on old reddit and has a simple on/off toggle.
Thank you.

Flat-out doesn't work with old.reddit, and on the redesign makes all dropdowns unusable.

0/10 unusable

Looks nice. However it doesn't completely work with the update. Otherwise would be 5 stars.

finally

Great addon, minor issue: The sidebar does not get the dark theme treatment and still are white.
