The first extension I download when on a new device. Super customizable, I've used it for years on all my devices and recommend it to everyone.

Been using this free app for so long that I just donated because I find it really valuable.

In principle, I really like this plugin. The dark mode is super comfortable. But, as others have reported, many websites experience a lot of latency and Firefox suddenly needs a lot of GPU power, even if the plugin is not activated for that website.

Can't use the browser without this extension. Dark mode in any site is just awesome.

Slows web pages to 2000 dial-up level

Ist eigentlich ganz gut für die wenigen Websites, die noch keinen Darkmode haben! Aber manchmal kommt es verständlicher Weise zu darstellungsproblemem 8 out of a 10!

Have A Great.

Since latest update the add-on is crashing my tabs. When it doesn't crash my tabs it's extremely slow and uses a lot of CPU.

Great extension.

Makes website loading too slow. Almost unusable with modern websites. Dark theming is good.

Works really well for the most part, and on a lot of websites it completely looks like the site is using their own dark mode. However, it's not very good at detecting when sites have their own dark mode, so you have to manually disable it sometimes. Also, sometimes it doesn't properly invert some things and you'll have to change the filter mode or disable it for that site. But having dark mode for everything is worth the small bugs
