Dark Reader adds a good 5 seconds of lag to interacting with the web (including: website loading, website interaction, tab switching) for me.

That's why I use "Dark Background and Light Text". Color schemes are not as good as Dark Reader, but it doesn't noticeably affect performance.

For those initially confused (like me): this is also a Firefox extension -- https://addons.mozilla.org/en-US/firefox/addon/dark-backgrou...

This is lovely. Thank you. PS... I just switched to FF after countless years with Chrome. It was the container tabs that finally won me over, and the rest of the pros are icing on the cake. Wonderful.

Most of those extensions work by just inverting the colors of the entire page. Pretty unideal, compared to an intelligently-written dark theme.

Dark reader by default uses a different approach than that, but it can fallback to inverting colors IIRC

Extensions are also a huge security liability; I install very few of them these days
