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

I do recommend this addon; in general it works extremely well though there are a very few minor circumstances where it will obscure web page content. For example, at the time of this writing, if you open a review page on Etsy, it will show all reviews as 5-star but if you turn the reader off, it can be seen that it had simply changed all the stars in the same way. So sometimes I have to turn Dark Reader off, but very rarely.

Indispensable

Honestly it is the best, especially at night where I get headache from all of the white light coming out!

I agree with what MrTwisby said in his review. FireFox moves like a slug with Dark Reader Ext active. I have used it for a long time but it is so bad now, unstalling it.

Excelente extención la han mejorado con el tiempo.

Maybe someone can help.. I don't have this little icon to adjust brightness, contrast etc.
