Great Addon for webpages that don't support the dark mode.
I use the Addon with default off and turn it on for specific websites

Finde endkrass dieses Extension!! 👍👍👍👍

Exceptionally useful and very well made indeed. I see some reviewers say it slows down Firefox but I haven't noticed any decrease in performance.

Worked great, much better than all the other extensions. I just deleted it because I found out the website I was mainly using for supported dark mode :P
