Works very well overall. What would make it a 5-star review would be if it didn't slow loading webpages. Otherwise I have no real complaint. By far the most user-friendly, while still customizable.

This is the best dark mode extension i've but im experiencing an issue where my firefox home page gets inverted to white, even though i have the firefox dark theme enabled. Pls look into this.

Cool beans

My eyes would like to thank you for this extension - it helps a lot those who want to browse the web in a more comfortable, eye-friendly way. There must be a Thunderbird version as well - is it ever planned?

Great features and really saves my eye strain. Unfortunately it makes your browser extremely slow. Some sites take over 30 seconds to load with this add-on enabled. When you disable the add-on the sites load fine.

This add-on attempts and almost always achieves an incredibly difficult thing. Websites are incredibly varied in the way they implement CSS so adjusting it on the fly is a monumental task. This does so in a very intelligent way and mostly works well. There are situations where you have to tweak the settings a bit but I don't see that as a negative. The fact that there are so many ways to configure things is a huge plus. A big thanks to the developers and contributors to this project. You're doing an amazing job!

Used to really enjoy this addon, but has been very slow and several sites have stopped loading sections properly since latest update

UPDATE: 24-nov 2020: now even salesforce is get properly dark 🌘💪😀
Thanks, still the best "darkning" tool 🤟👍

Since last update of 24-apr 2020, the add-no no longer works properly on FaceBook. FB default images ( e.g. Like or Shortcuts to Messenger ) don't show up any-more???

Also other sites have similar problems, looks like "radio-buttons" don't work any-more. The radio-button options are not showing???
