It works really well for most things, but if a website has a Disqus-style comment section it won't automatically turn it dark and I have to turn dark mode off and on for it to work. I have this problem on SBNation sites and on Angrymetalguy.com

THANKS FOR YOUR SUPPORT

Breaks mobile browser

Výborné.

mantab, bro

Work much better than other similar extensions, and no need to micromanage styles for every website. Sometimes I do encounter problems on certain sites, but it's easy to switch theme generation mode and find something that works.

It always work fine, while similar extensions not.

This is cool! :)

Causes significant buffering for youtube.
Has a tendency to wrongly mutate the webpage or ignore existing dark modes.
When disabled on a website it could potentially permanently break the default styling causing black text on black background. This requires a full on hard reset of Firefox

Lately it interferes with too many websites. So many sites, especially for news, use the "read more" button to see beyond the first paragraph or so, but I can't click it. I have to disable this addon before it works. I wish dark mode were more of the default across the web because it's so much better for your eyes.
