Completely killed my browser performance, even after disabling and then removing the addon. Closed the browser after that and saw my CPU maxed out and my RAM being flooded to the brim until all background tasks were shut down after a while.

Didn't work for me.

Wonderful app, Lot of options! And very friendly to use. Love it!

I can't enable dark mode for guides.github.com if I've disabled it for github.com

Warning about QR-Codes with this enabled. The QR-Code will not be scannable in some sites whilst this is toggled on. Half the websites I use 2-way authentication for do not work with this on.

Otherwise a great add-on, a must have.

Сайт vk.com долго загружался из-за этого дополнения (вплоть до 15 секунд). После отключения всё стало ок, 3-4 секунды. На остальных сайтах всё ок.

Perfect

I've used this for about a year+ on both Chrome and Firefox. It does an excellent job of converting most websites to a dark theme. It really reduces the strain on your eyes in a dark environment. I'm very happy with this app.
